Answers come from tanghoong.com and nothing else — including a costed verdict on your own project, which may well be "don't build it".
Start with one of these
Will — answer from the text of the site and name where each answer came from · cost an idea with a build / fix-the-process-first / don't-build verdict · convert currencies and count real working days, including Malaysian state holidays.
Won't — discuss rates, promise a date, or state anything about him that is not written on the site. If a claim trips the honesty rules you get a refusal instead of the sentence, and it is counted on the metrics page.
