I'm in North Central Florida, so unfortunately I don't have any useful recommendations. There's plenty of Lumber Liquidators in Florida. They are, at the very least, a good place to start looking and getting some pricing info.

One of the problems you will likely run into is that most houses in Florida are built on a slab and don't have any subfloor, so you'll either have to put in a subfloor (can get costly) if you want to do nail down and finish on-site or you'll have to do some kind of pre-finished, engineered floating floor. I had a lot of installers recommend against glue down because of the humidity levels in Florida causing too much expansion of the glue itself (rather than the wood).

Good luck with your move! I lived in south Florida for a long time. It's terribly fun and you'll love the beaches... just stay off the freeways. Ha.

Wood is a BAD idea in Florida! However, if you like the "look", there's an excellent new tile out you'd swear was wood slats! It comes in what must be 4x18" pieces. I rent / rehab / flip homes & even I was very impressed with it. Remember, your putting this on a concrete floor base.... no wood.
