You have to go to a district qualifier to qualify for the national qualifier. If you qualify there you go on to the JO. If you don't qualify there you can go to Disney for Club Championships and you can qualify there. AAU has or will have the locations of the qualifiers. Last year I believe districts were in Tampa, Miramar and Jacksonville.
Not sure of the clubs in Tampa, I know they have some. I suggest you go on BAYTAF's website. They hold a memorial day meet every year in Tampa. If you look at last years past results you may see a team that is near you or they might have a email or number for the coach. You could contact him and he could steer you towards a local club. Or I believe you can go to AAU's website and they have a list of clubs.
