No - AG - an FAA instructor is not qualified to do this flight with you.
Nearest JAA for MIA would be Naples Air Center in - would you believe - Naples. A short flight across from MIA area (Westbound).
The ONLY person there that is qualified to do what you need is Andrew. Call 1 800 226 4000, extension 210.
If you fancy a run of about an hour North from Miami drop me a line and I'll help you with what you need.
Change to PM if you wish.
Enjoy Florida.
