It depends where you are. I know the Medical College of Georgia is a little over $10,000 a semester for the first year, then you gain residency and it drops down to a little over $3,000. Also, if your state doesn't have a particular program, I am pretty sure that you can be considered an in-state-student to schools in any of your bordering states.
P.S. Don't look at SC schools, they are expensive. MCG is the best price I have found for DPT and Western Carolina has a really good price for MPT.
