I would highly recommend Cracker Boy Boatyard in Ft Pierce, they have a sister yard in west palm beach, but much more expensive and more restrictions.
In Ft Pierce, can spray and sandblast. Very skilled workers on site, or can completely do it yourself. If you are going to be more than a month, negotiate a discounted rate....
We spent 9 months there during one refit
and 7 months there during another refit
, two different boats. Very inexpensive and fair, good advice and help, excellent painter and carpenter
work out of there if you need help...
Best of luck.
