I also suggest the Cornish X. You've done quail, so now do chickens and see how you like them. To me, it makes sense to compare.
I did a quick Google on "chicken hatcheries in Ga" and got five hits. I don't know if any are within driving distance or if they have what you want or even sell to the public. It might be pick-up only. I'll leave some of the work to you.
Are any feed stores still having chick days near you an do they offer CX? You might compare the cost of picking up live chicks from them that have made it through shipping to the delivered cost of shipped chicks. and the risks of shipping
Most of the major hatcheries will ship them to you through the mail, though the more remote you are the longer that might take. They normally fly them to a relatively major airport then truck them to your local post office. The the more direct the flight and the fewer sorting offices they go through the faster the shipment. I sometimes get mine the day after they ship, though a couple of times it's taken an extra day. I don't worry about which hatchery is closer since none are within driving distance. I use a major hatchery and see what the total arrival cost is for what I want and availability when I want it.
