What you are asking, is like calling a tattoo parlor for an "on phone estimate". Any contractor will NEED to see it first hand. With the lip/backsplash you have, that will involve numerous cuts/mich matches. IT is too hard to tell, even with pics. SQFT range in price form the quality work you want done, to the materials it is done with, single slab, single back splash, cut tile, etc etc etc...
You are in TX,there is NO shortage of contractors willing to meet when YOU have the time.
