Welcome to the forum. I think you will need your drivers license to to ride a motorbike on the road in the Peach State, so plan an off-road build for now.
These machines are far cheaper than a quad or dual purpose motorcycle, and you learn a lot during the build.
With a used bike in good shape, you can build a 2 stroke bike for under $250 if you shop carefully.
