Welcome to allnurses!
There are a bunch of existing threads here about nursing employment (and life in general) in FL -- have you looked at those? That would be one place to start. If you are coming from a Northern state, it's pretty much a given that you will be shocked by how poor the pay and benefits are for comparable work in FL, and the cost of living is still pretty high. I grew up in FL, left the first chance I got, and would never consider living there again. But, obviously, lots of people like it.
I suggest you browse through the FL forum (under the 'US" tab at the top of the screen) here and check out some of the threads.
