I live in the upstate of SC and get to Atlanta routinely. I'd start by going to the ARRL website and ordering one of their study manuals. You'll have to start with the Tech, but I'd go ahead and get the Tech and General books. Read them, study them, and go through the exam bank questions in the back. You can also take online exams to practice. These all have the actual exam bank questions so by the time you take the actual exam, you should have seen the question before. I strongly suggest not memorizing it, but learning it. I paid $10 to take my test. Once you pass the Tech, you can go ahead and take the General class exam. That's why I suggest studying for both. Neither is difficult.
Once you've studied up, you should be able to pretty easily find a location to take the test. Many clubs offer them once a month or so. You may end up having to drive an hour or so to a larger city. If you're kinda close to Atlanta, I'd also suggest stopping by Ham Radio Outlet (HRO) on Buford Hwy. They should have the manuals for sale there, along with other equipment and will be happy to help you.
Drop me a line if you have more questions.
