Comparison of different kitchen renovation providers?

[serendipiteez 0]

We are looking to entirely redo the kitchen in our new house. We want a modern, minimalist style. 

Attached is what it currently looks like. I have a few questions:

(1) Is there a comparison of different vendors in Singapore?

(2) What is the approximate amount it would cost to put wooden counter-tops, change the cupboard, and the tiles on the wall?

(3) How long will it take approximately? 

I know it is all very case specific and boils down to personal taste but looking for approximates. Thank you very much.
