Ninjitsu won't be a big help. Hopefully you can wrestle somewhere. If you're still in school and they offer it, join. Kick boxing or Muay Thai would be you're next skill to learn.
A city as big as Orlando should have a BJJ studio somewhere. Gonna need alot of everything to make it as a pro so check that out.
Good luck with it and hopefully we see you in the octagon in a few years
