I am not in Central Florida so i do not know the local scene. A small breeder that does sell some club calves is Ste-Bar Ranch: http://www.ste-barranch.com/. You may wan to check them out and get leads on other breeders.
If you want to buy from a big reputation breeder look at the Southern cattle Co. up in the Panhandle: http://southerncattlecompany.com/.
If you want to go further afield then you can find numerous breeders in Alabama or Georgia.
