You can download a file of all preparers with PTIN's in Georgia, then sort it by ZIP Code.  Alpharetta is a town in north Fulton County -- there are more than 100 preparers listed there in ZIP Code 30004, another 100 or so in 30005.  Many of the listings have phone numbers and websites.  People in Georgia are friendly. I bet if you called ten at random, you would get twenty leads.
