Without a proper jig and some other really expensive bits you'll strugle to build a decent frame. If you're interested in doing a course. Martyn of http://www.downlandcycles.co.uk/Downland Cylces offer a 5 day course as does Dave Yates but there are currently no available spots but you can register interest incase someone drops out. Expensive but worth the money for your own custom frame and the skills to start building frames.
I was going to suggest www.ceeway.com for parts but I see the link above www.framebuilding.com also goes there. They are probably the best.
Reynolds will also supply direct. http://www.reynoldstechnology.biz/
