Caye Caulker fishing guides

I have been visiting Ambergris for some time and Fly fish the flats with a local guide who has become a friend, my wife and I discovered Caye Caulker last week and love it, do you know any of the local flats guides at Caulker? I dont like to go thru tourist companies but prefer to deal direct with the guide, any contacts would be much appreciated.

I spoke to an old friend in Caye Caulker & he gave me the name of Porfelio Guzman who is a seasoned Flats Guide. I call but go no reply at 226-0152.
