fly fishing puerto rico

Hey guys,

Ill be going to Puerto Rico for work roughly in march. Ive been doing a lot of research on taking a day or so to fly fish and i cannot find any information for a do it yourself trip. Ive seen some fly patterns and rod size recommendations but i haven't been able to find any info on how to do it by foot. Everything talks about hiring a guide, but if i don't have to id rather not. I'm not looking for anything species specific, but i would prefer to try salt or fresh for peacock bass. If i hire a guide for the day I'm definitely going to target tarpon/snook. Any help whatsoever would be greatly appreciated.
thanks
