I'm also in South Atlanta (Henry County) and none of those links helped me. You can call vets around your area, they have lists of exotic vets, the doctor I work for is currently finishing up building her own clinic and not taking new patients, but she does see pigs. She won't open for about another month or so, but if you need her then, feel free to PM me and I will give you her info. Other than any of that, the next closest would be Atlanta.
There are also rescues in Atlanta who can refer you to the Vet they use, but being in Newnan, I doubt that will help. My Vet is also about HR 30 Min's away so it would be easier for you to probably go to ATL.
