Other than this startling revelation of a producer of buffalo mozzerella, cheese is just about impossible to have made/make in FL- high temperatures and humidity nix both healthy milk-producing animals and the process of cheesemaking. I've been trying unsuccessfully to find local cheesemakers in FL for a project, and after much research and talk with artisanal distributors throughout the country I've given up.
The closest I'm aware of is Sweetgrass Dairy in Thomasville GA (near Tallahassee along the FL/GA border), which makes both goat and cow milk cheeses, though a little googling revealed a Winter Park Dairy in Winter Park, FL producing a raw cow milk bleu.
i think that i may have actually seen a couple of these in lake county (around round lake road and wolf branch) ?? they looked like real buffalo though.
i don't think there's a big cottage industry as of yet in making cheese though.
maybe see if you can contact this fellow:

As posted a couple of days ago, the only two places that may make mozzarella here are O'Stromboli on Corrine Drive at Old Winter Park Road and Harmoni Artisenal Market in College Park.
I don't know what kind of milk they are using.
I'd have to say that your impression of water buffalo everywhere probably isn't accurate -- I'm not aware of their widespread use in Central Florida at all.
There is only one commercial cheese maker that I am aware of in the area and that is a company over in South Brevard. The details escape me, but I probably have it in my files at work
