I would suggest contacting Black Fly Outfitters in St. Augustine. It is owned by Vaughn and Jean Cochran, who used to live here in the Keys (actually across the canal from me). Vaughn used to guide and now is a full time artist, and they both run the store. You can easily find them online, I don't know their number off hand. They should be able to steer you in the right direction in terms of a guide in that part of the state. They are good people, much like the folks at Little River Outfitters. Good Luck.
