Fly I would really check out the 350 area before the move. Competition is very tough and a federal permit is needed to operate in the Park. Guides have to leave 3 hours before daylight to stake out for a good tarpon spot. Bonefish are larger than most other places but very difficult. Bait fishing for these is much easier but most the people with the money want to fly fish and very few cast well enough to catch fish. Living expenses in the Keys are out of sight. You will loose more days to weather in winter than you do now on the coast.

The great part is the weather and the miles of flats to explore , spend some time in that area , I hope It all works out for you.
