First check out the local community colleges and Recreation Centers to see if they have an into to flyfishing class. There is so much more to flyfishing then just casting. If not maybe a local flyfishing shop offers a class. There there are guides. But just learn to cast is just a start.
I like Lefty Kher's books and videos, check out the local library to see if they have any videos.
Well GL with your endeveor. Let me know if you have any more questions.
cheers
