Hi J1mbo,
I know absolutely nothing about the school you intend to go to. BUT just a quick word of warning..
I can promise you that if you are instructing in Florida in the heat of the summer, the very LAST thing you're going to want to do in the evening is study an intense DL course. I don't care how dedicated you are, sitting in a C152 when there is a heat index of nearly 40 C is painful..!!!Believe me during the summer it's no fun at all.
If I was to go down the instructing (hours building) thing in the US, then i would either go somewhere out of Florida (bit cooler), or enrol at somewhere like Delta in Sandford that do the JAA side of things before the FAA.
Whatever you choose the very best of luck to you,
Captmav.
