Try SkyOps in St Pete - otherwise you'll have to travel to Crystal River/Brooksville (John Jerkins) or Kissimee Flight School. There are a few more alittle farther out (Ft. Laud, etc...) but these are the closest.
One mans opinion.....
You'll probably find it cheaper to get your PPL in fixed wing first... then chase your rotor ticket. Rotor lessons (300c, R22, etc...) per hour are about twice that of fixed - so to learn the basics of general aviation theory and practices, it's best to do it at the cheaper rate.
