Use the LIVE CHAT whenever is possible, I sign in Zendesk Chat and I am ONLINE every day up to 14 hours, I answer 90% of chats in less than 1 minute. If you have files to send, send via email.

Do not make phone calls, is difficult to deal with customers via phone since most deals require sharing links, photos and other files. If chat bar show OFFLINE, it means that I am sleeping, driving, some important meeting or other activity in which a phone call would be even more disturbing. Leave an offline message via chat or send an email and wait.

I reply to every email once I return to computer, and when you see my reply you are advised to visit website again and contact me via LIVE CHAT so we can discuss quickly your project requirements, instead of replying me via email too. I had many cases when people never replied back at my emails, it may be blocked by your SPAM filters, in this case contact me again via live chat when I am online.

Post public comments if you want to praise me (after purchase or consultation), suggestions, questions for other website visitors, or have information to add that may be interesting for other visitors.

Do not post comments to ask questions that require MY answer, example “I want to buy this, how I can contact you? / please email me your PayPal address“, instead contact me yourself via chat or email. While I do get email notifications for every comment posted, 90% comments are posted by spam bots rather than human visitors, so I seldom read comment notifications. One day I noticed an 1-month old comment posting his email address waiting for me to contact him, I emailed him, but was too late.

Please post comments to reply also comments left by other people. Do not leave all communication to be ONLY between me and the 2000+ people who visit my website daily.

Do not post comments in Contact page!
Please post comments in the relevant page, for example house builders in Philippines post your comment in House Plans page or Philippines page, while for questions about Singapore SERS programme post your comment in SERS page.


Zopim live chatI created website in 2009 to showcase my hobbies, I accidentally discovered chat software in 2012 and added it on my website to talk with visitors, make friends with similar interests, get feedback about my hobbies and works, exchange information, etc. The chat helped me also to get hired by people and get paid to do various works, or to understand market demands and offer suitable products for sale, turning my hobbies into money-making business.

Do you stay at computer all time to greet visitors and answer questions?

NO! The chat software pop-up and greet visitors automatically, as long I am online. Only if you type a message in chat, my computer rings. I stay ONLINE as long I am home and not sleeping (occasionally I sign in from phone when I am not home), but I do not always stay at computer, and if it rings I run to computer to answer you as fast I can to answer you. Of course this is not always possible, 5% of chats remain unanswered. But you can always leave your contact info to answer your questions when I return to computer.

This is why you may see chat pop up multiple times if you visit website repeatedly. If chat did not pop-up many customers would not even realize that there is a chat available. If you do not need help, just close chat pop-up, do not reply “no thanks” and make my computer ringing unnecessarily.

The robot can only greet visitors, cannot read your messages and reply, any reply you see is human, written by me.

How many people visit website and contact you?

As 2019, per month the website have ~60,000 visitors, ~600 contact me via chat (90% of chats I answer in less than 1 minute), few more contact me via email, Hangouts and Skype, ~60 buy something or pay a service, while the rest are thankful for free information offered on website. See full statistics.

Do you get paid to chat with people? Do you help people for free?

I am NOT employed, affiliated with any government or company, or get paid “to help people”. I am independent, this is my personal website and only YOU can pay, for example if my chat with you helped you to decide to buy a $500,000 property, I appreciate if you can donate to paypal @ whatever sum you like. Take example from this Indian who PAID me $20 for architectural consultation.


While chat consultation is usually FREE, research, drawings and database services are NOT FREE. This is how I make a living. If you are NOT PAYING for any service you are advised to not stay in chat too long time.

Students feel free to use information provided on my website, cite it in your research paper, but if you need additional help you are advised to use Google and get information yourself, do not contact me and ask DUMB questions (example).

Note: a small number of retarded children are responsible for about 20-40% of chats, children who do not realize that disturb a BUSY man from doing his business, some thinks that this is a bot chat and can spam any messages, including swearing and sexual harassment. The worse happens when a child message me from classroom and once I answer him to see if is a potential customer, he tell to schoolmates to message me at same time, making me to miss answering customers that were unlucky to be with me when kids start spamming, making me impossible to work at the projects I am paid for, etc. Kids often rate chats as BAD if I do not keep conversation going on with each one, if I tell kids to STOP because chat should be used ONLY for professional enquiries, they close chat and start another chat after few minutes or next day, pretending that have a project, purposely to annoy me.

I am sorry to all customers if I reply rude or not reply in time, because I was distracted by children misbehaving on customer service chat.

This is what I see at my side when a customer message me

  1. Hello,

    I will like to place an order to Nicaragua. However i will like to know if you accept private pickup if you don’t
    offer shipment option to the delivery location? My method of payment is bank Visa/Master card. It will be
    appreciated if you return my email with a price list of your products.

    Thank you.

    1. What are you ordering? All my products are digital so cannot be shipped or picked locally, just make payment via website system and you receive automatically an email with file download link.

  2. Yesterday, while I was at work, my sister stole my apple ipad and tested to see if it can survive a thirty foot drop, just so she can be a youtube sensation. My iPad is now destroyed and she has 83 views. I know this is totally off topic but I had to share it with someone!

  4. Are you looking for powerful advertising that doesn’t charge a fortune and gets amazing resuts? Sorry to bug you on your contact form but actually that was kinda the point. We can send your promotional message to sites via their contact forms just like you’re receiving this message right now. You can target by keyword or just execute bulk blasts to sites in any country you choose. So let’s assume you want to blast an ad to all the interior decorators in the United States, we’ll scrape websites for only those and post your ad message to them. As long as you’re promoting something that’s relevant to that type of business then your business will get awesome results!

    1. What do you say means sending unsolicited emails to people who did not agreed to receive promotional emails = SPAM! I won’t do that!

  5. Hi There,
    Just surprised at why you are entertaining all these non-nonsensical posts on your comments page. Why not put a captcha or spambot to prevent spammers here?
    And I am here because I was genuinely looking for a SG car database. Might make a purchase later on.

    1. A captcha is useless, because I already use Akismet which block 99% of the bot / spam comments. The comments that appear on website are left by human visitors who would solve any captchas I put. Moreover captchas don’t work over VPN and there are legitimate customers interested in my services that use VPN and would like to post comments.

      Is better to not have captcha and manually delete spam comments left by humans. Since few months ago been too busy with projects for PAYING customers + some personal problems unrelated with business, thus no time to keep an eye on comments. I missed to reply in time legitimate comments, example

      But why do you say that I am “entertaining“?

      To avoid this happening, please contact me via live chat in lower-left corner of website, instead of comments.

  6. Hello, Our engineering team is trying to load the databases you provided and we are running into a problem with the July 2019 and Dec 2019 spreadsheets. The Dec spreadsheet doesn’t contain some of the vehicles that are on the July spreadsheet. We cannot combine the speradsheets because that would cause duplicates. Are you able to provide one spreadsheet that encompasses both Dec and July vehicles?

    1. You left comment in WRONG page, and at bottom I clearly explained the reason for which I provide 2 files and the problems I have in combining. If you have any solution let me know.

      Since you didn’t purchased full specs database to motivate that you needed all 230 columns, but trim/naming only, what was the reason for purchasing instead of higher quality database that do not have such problems?
