you should try Sulcata grove, you are near them. They are one of the only nurseries in Florida that offers the Pitogo, they also have some of the other varieties you are looking for.
We searched for a few years for a Pitogo and the only 2 nurseries that sold them in Florida wouldn't ship. We finally found one from a private collector friend of ours in Miami. It hasn't fruited for us yet and it actually froze to the ground this past spring. Maybe next season if we are lucky we will be able to verify it. The other place was Going Bananas in Homestead. Good luck.
