If I was you I would seriously check out Mike Roberts Bows. He has a website, and is based in the UK,(so it would be cheaper for shipping) he makes top notch bows of all kinds, not just english longbows.
There is also Del in England he has a site/blog too, I just can't think of it at moment, I'm sure he would/does make more primitive designs as well. He is on this site and makes top notch bows as well.
If you decide to go down the US path, there are so many good bowyers it isn't funny. Best bet is to find the type of bow you like by looking at posts and contact the bowyer directly.
