hi,
i am a recent (may 2004) migrant to florida, from a dry western state. i can speak to your situation. i think you'll be happy once you get through the modest hassles and settle in here. the system is quite sensible and reasonable. beats the hell out of "no, period" like in much of california, for example, or "sure, whatever, a paper bag is fine for that cobra" like in, say, texas.
first, on the legal side, the permit is easy to get. i had my wife and mom write letters addressing my competency and experience. (i'm now 35; my mom described taking me herping as a teenager to collect rattlesnakes for my collection; my wife now lives with my snakes and occasionally sees me handling, like when assisting with veterinary-type procedures). i wrote a letter for myself as well, describing my experience, collection, motivation, etc. "i just want to comply with the law" usually goes over fine with law enforcement types. finally i added some purchase invoices from various reptile dealers, showing i'd bought a variety of venomous snakes over the last few years. but that was just fluff, and not necessary. as an arizonan i doubt you've been able to buy snakes from, say, glades. as i recall, that wouldn't be legal...
note that i had/have ZERO "professional" experience, it was all hobby, but pretty deep and wide. the $1000 bond is only for exhibition, as the previous respondent noted. to keep but not exhibit, it's $100 a year, per address (the permit is only good for the address inspected - it doesn't transfer if you move in-state, you have to reapply and repay).
the biggest hassle for immigrants is the cage inspection. the snakes can't be there yet. so, move your stuff to lauderdale, set up the herp room, and leave the snakes in arizona with a buddy who can freight them to you (e.g. a delta-recognized known shipper). or ship them to a friend in florida who's already permitted, if you can, and he can hold them for the 6 weeks you'll need to wait. anyway, once the game warden looks at your cages the permit comes pretty quick, maybe a week and a half or 2. it takes about a month to get the inspection though, once they receive your paperwork and check.
all the cage and room specs, and application forms, are on the FWC website.
i brought about 30 snakes (100% crotalines) with me. mainly western forms. with all the air conditioning here, homes aren't that humid. my snakes are fine so far. i don't have any extreme-xeric forms though. however, it seems that plenty of people here keep them, many problem-free. perhaps others can speak to this. also, the power does go out now and then (look at what charlie did), and the humidity shoots up at those times.
cheers, and good luck.
