There's another very serious element to consider about moving to Florida. Rentals and housing prices are soaring in Florida. Low cost housing is especially hard to find. At the same time, well paying day jobs are hard to find, too.
There is a lot of work in the service industry...hotels, restaurants, fast food, and jobs in the health industry go begging...any kind of medical work is fairly easy to find. But service jobs are notoriously low wage jobs, plus, because in Florida service work is seasonal, you may find yourself out of work in the summer.
On my side of Florida, most lawn care work goes to Hispanics and Haitians. Many jobs are available for skilled trades such as roofers, dry wall installers, plumbers, electricians, tile and flooring, hurricane shutter installers, and air conditioning installers and repair specialists. There is a huge construction boom here, both in residential and commercial real estate and in highway construction. But do you want to toil all day at a hot construction job, then play late into the night in some smokey club?
I don't know your background, training, or interests other than music. I do take it that you WILL require day jobs and a place to live. If you want to come to Florida, please check out these details first and come with enough money to cover expenses until you find work.
One good way is to read the web sites of the city newspapers you are considering. Read classified ads for jobs, rental ads, and club ads to see how many clubs there are and what type of musical acts they prefer to book. The more knowledge you can arm yourself with before you come, the more sucessful you are likely to be.
Also, know that some people come to Florida,but are unhappy because they tire of the nearly endless summer, the large percentage of "senior citizens", the traffic, no mountains or even hills, and other factors that make them homesick. Still the endless summer is exactly why others come to Florida and love it. Be aware ahead of moving that not all of your band may like it here and may not want to stay.
