Hi g2hong,
Hope the list does help you in choosing one.
We're final with 1 of them already, JGH. After the annoying We***n incident, I was very very skeptical with all the IDs in IMM (JGH was at IMM but now moved to TradeHub). Furthermore, they're not the cheapest, but after meet up, the designer we're liasing with, Sam, is very sincere & honest. He also able to come up with ideas & advices we were not aware of. We've got him from a friend who has just done up his reno, went to his place and impressed with the results. They're a bit slow in responding, but leave a message, he usually revert back. When we first met, we only told him some ideas, the quotation he sent, not only a 2D layout design, it came along with a hand-drawn 3D perspective of 2 areas, which looks really nice. If there are prices that you think too high, you may highlight to him and he'll try to revise, if couldn't he'd suggest a different design that use less materials but still look as nice, we told him upfront that we have quite a tight budget for the reno, but so far we're happy with his suggestions and ideas. Although JGH from what I read (in RT forum) is more of a contractor, we're pleased that he can proposed design ideas that suit our needs.
The other one, IDL, was the other top consideration, as the price is very very attractive, the guy we're liaising with is the boss, hence, the price is very very flexible, but he's more of a contractor, so you have to tell him cun-cun exactly what you want and need, very good for small or simple renovation. The quality also pretty good, we saw it at our neighbours' place who has engaged him several times for his parents, brother, sister in law.
But, we decided on JGH, as we do like his designs, and how Sam can workaround the ideas to suit our budget without compromising the quality. We've confident in him as we have seen the end product at our friend's house
<font color="0000ff">Just my two cents, know what you want to do with the renovation, be it small or a major one. Then do a bit of a research on the pricing, Googled, read forum, etc. A quotation is no-obligation one, you have the right to ask them to send to you, for our case, if the ID refuse to give us a rough quotation, we won't consider them no matter how great ppl say they are (don't buy a cat in the bag, renovation is not a matter of buying a candy). Upon seeing the quotation, don't fret when you're quoted very high, put yourself in their shoe, you would want to make the highest profit if possible. But you can always share with them that you have other quotation of a better price, or you saw a direct supplier selling at a cheaper price -- of course, be reasonable & honest with the price. If they're sincere and keen on getting your business, they WILL try their best to revise for you. Even if they couldn't (restricted by their company), they'd try to compensate the difference with other FOC items

Happy hunting
