Don't know about Florida. But, Chandler Air Service in Chandler, AZ does aerobatic training in a Great Lakes 2T-1A-2 biplane. Basic 10 hour course is 2 hours ground and 10 hours in the aircraft. Solo rate $195, dual rate $275, ground $70/hr. So all in about $2890 plus if you have cash they usually give another 10% discount. At the completion of the course you can solo the Great Lakes. You will learn aileron rolls, slow rolls, loops, immelmanns, split s, cuban eights, hammerheads, spins, snap rolls, and inverted flight.
I've been through the program and also instructed it. Some of the best and most fun flying I have ever done. Highly recommended it. And yes it will make you a better pilot overall.
I'd call around the Florida schools and see if any of them know of any aerobatic schools like the one in Chandler.
Good luck!
