I dunno. Sounds like the right approach. Is it possible he lost your number/address?? Have you called him a second time, just to be sure??
If he doesn't have a shop you can go to, he probably is a one man fabricator ... working in his garage.
There are a couple of alternatives --- under granite in the phone book, look for the "yard", the distributor. Call, ask if you can see some samples, ask if they can recommend a fabricator.
Or. talk to your cabinet supplier ... he probably knows who does good granite work.

In another thread, you suggested a price of ten thousand dollars for seventy square feet of granite. For mid-grade granite, I pay $55/s.f. plus $190 for custom edging. Underslung sinks run around $300 to $500. So my cost on your countertop would be about $45 hundred. I would charge you $5,200 for the countertops, and another $1500 to 2,500 for the tilework.
These prices are Calgary, Alberta, Canada. But by casual observation, they're not too far off for the rest of Canada and much of the USA.
