Reputable breeders/shelters/rescues in FLA

Hi everyone, my name's Kila. I currently own a female APBT, named Lexas. I am looking to get another APBT or Am. Staff. Preferably a blue. The dog has to be a male though, b/c I don't want to bring a female pit bull into my home which already has a female pit. I would greatly appreciate anyone's help in finding either a breeder to buy from or a rescue/shelter to adopt from.
