my 2 cents. take or leave:
* severely cut down the copy up top. e.g.: Athenian Marble has specialized in cultured marble since 1969. We have 50 employees in a 67,000 sq ft facility to serve your needs!
* add the A+ BBB rating as a very simple graphic--instant credibility (even I know what that is!)
* 3 calls to action below:
1) Call (phone number only)
2) Visit (address only; map seems extraneous; maybe include the photo form the "About us" with the building facade so people can find it easily when they drive there)
3) Email (deprioritize this--I assume most people pick up the phone for info on marble; maybe even get rid of the form and just have an email address)
I would refrain from using phrases like "Are You Ready?" and "Let us help you." In particular, "Are You Ready" could turn off someone who's just looking for info.
BTW, the "see all photos" page should feature photos more prominently. It has a ton of text up top. I imagine photos are very important for engaging customers.
