Today, your best bet is to go take a framebuilding course.
Here's another idea. Like Ness said, you could go ahead and get the Paterak manual right now and try to learn a little on your own. Equipment is expensive, but if you plan on taking a course you probably want to do some frames on your own afterwards. So, why don't you just get an oxyacetylene tank setup and some basic stuff and give it a try? If you find it taking too long to learn everything, you could always speed up the learning curve and take a course.
That's great advice. If you have a frame or two under your belt already, I think you'd get a lot more out of the course than someone who is doing it all for the first time.
