I believe if you want granite tile you are going to have to go with a flooring/ tile company. Centex, Old Stone and others are going to deal with slab granite vs. tiles.
I'm a fireman and do some handyman/remodel stuff on the side and did granite countertops in my own house a few years ago... if you'd like, I can send you pics of my completed kitchen and countertops and you can decide if you'd like me to come out and bid yours. aggieemt at Hotmail dot com.
