I can't give a personal recommendation, as I don't have a Standard (though I am in Florida). You can start your search by checking the breeder list on the Standard Schnauzer Club of America's website, found here: http://www.standardschnauzer.org/breeder_info.htm
The way their list is set up right now, you have to search it yourself by using your browser's find feature. CTRL+F and search for FL. Some have websites, all have contact info, so you can express your interest.
