I'm not sure where in S Florida you are, but I found this list by goggling "kiln repair near Miami, FL" and there were several other sites that showed up too.
It also depends on who made your kiln, etc. For instance JenKen Kilns is in Lakeland, and they're very nice people.
If you look for the maker & contact them I'm sure they have a list of recommended repair shops too.
Good Luck!
