So except for Collier County with Naples (where rich retirees live) the Florida scene is not that attractive $$wise for income levels.
However, there are lot of fine ladies who live in Florida and have donations ranging from $300 to $500 or even more and doing well. Since you are only visiting, it will take couple of visits to get visibility and have a few regulars on board and get some rave reviews. Also, there are factors other than donation that can sway guys to come and see you. Anyway, Good Luck.
