Lots of places to look. While I have never fished with a guide, since I have my own boat, I'd be happy to give you some contacts I know if you PM me.
Catching your first bone on a fly is and can be a challenge. First, the weather must cooperate, then the bones must be in a feeding mood, finally your guide must be able to put you on the fish. Remember, these bones are probably the most targeted fish in the world. Most have seen a fly so good and accurate casting skills are imperative to success.
Mangroves are excellent areas to target red fish and snook. If you get a hook-up at the edge of the mangroves, YOU MUST stop him from entering the mangroves; he will break you off! Bones and permit are usually target out on the flats, tailing in the turtle grass.
Giant tarpon are visually sighted and usually hooked close to the boat. Indigenous tarpon can be located in specific areas year round and are a blast to catch.
Tight lines and good fishing!
