Re: I have a junk neck!
If you go down the DIY road, you can pick upp boards from several places like StewMac and LMI. You can also get them from aiguitars on eBay--he's got prerouted ones for his funky inlay kits, too. While you're at it--replace the truss rod if it's bad. Follow the white rabbit Ryc sent you to for the tutorials, but also take heed at what MusiKron stated--you'll need special tools like fret level, sanpaper, stel wool, fret files, crowning files, edge dressing files, etc. Your best bet is to hold off and keep searching the bay--they pop up every week. Stay away from the seller MasGuitars--he's the most expensive chop-shop seller on there. You could also order a great custom neck from Ernie at ET Guitars--link in the vendor banners at the top of each Jemsite page.
