I'm also looking for renovator and contacted Mr Ken at Clementi branch. He is recommended by my agent. He's quite a nice guy, spend time talking and listening to us. Their quotation is quite ok but the materials that they quote is cheaper than others IDs (tiled, laminate, etc). That's why. I think it's most important to find out which material is quoted. But it's up to your budget, sometime we don't want to pay to much for expensive material.
