check out Ocshner clinic also. They don't have any kind of application fee or a limit to the number you can do. they will also reimburse you for the month's rent for the first rotation you do there.
I'm a rising ms4 at AZCOM and I did 5 months of rotations in NOLA last year and have my first 4 months of 4th year confirmed already. LSU and Tulane all require application fees (tulane's is expectedly more!) and they only let you do 2 rotations in their system. Pm me if you are interested in private docs in NOLA who take students.
