Florida is a very diverse market for tennis...the further south in the state the more seasonal it becomes. A lot of the South Florida tennis directors and head pros go north for the summer to teach at summer-only clubs. From Tampa northwards, we're a little more all-year but be ready for less than steady income as rain washes out a lot of the better teaching hours late afternoon and early evening.
I've worked as a racquet tech at many clubs and muni facilities in the Orlando area. We are more year-round if that's what you're looking for. If you can get a hold of the Florida Tennis Association, they publish an annual directory with club names, addresses, facility descriptions and tourney schedules. That might make a good start for posting some resumes. You've got enough experience to land something with a decent operation where you can make your mark. Good luck!
