There used to be a very good fly shop in Roanoke that had an excellent selection of tying materials. I don't know if it is still in business or not and I don't remember its name, although it did have Roanoke in its name. Northern Virginia should have some fly shops around and it would be worth your effort to find them.
I recommend going to a shop to check out materials and ask questions on how to use them since you are a new tyer. This will save you a lot of frustration and keep you from buying materials that you will very seldom use.
