If you're a first timer, depending on where you live get the blanks & components from either Fishing Tackle Unlimited here in Houston or you can order from MudHole.com- they're based in Orlando and the biggest in the game in supplying blanks & components to rod builders.
Check out the various rod building forums out there.
I've only built one rod and it was a fly rod. My BiL used to be in the business of developing and selling components to custom rod builders or to Mudhole & FTU as well as making custom rods for a few clients or friends. He was especially known for developing some different epoxies (ThreadMaster), special rod grips (he co-developed the first carbon-fiber rod grips- see pic below), and a few other things.
The rod I built, with the blank, components, and craftsmanship would retail for $750. But he basically looked over my shoulder the whole way and walked me through step-by-step, gave me tips & tricks, and so on. It wasn't difficult as long as you're patient.
Anyway, my point being that if you're the least bit handy and have the time you can easily make your own rods. Unless you've got a master to assist though, I'd start with one of the kits you can get at FTU or MudHole.com.
