seriously kakapo, hit up your local chain bookstore and pick up a few woodworking books and mags. The netz don't cut it. My uncle made a fretless six string electric bass that looked like claypools with the stripes of alternating woods, and a 5 string fretted bass with a whammy bar. Those were first tries. I mean, he had never tried anything so difficult, and he owned. They are a joy to play.
So in conclusion, after reading a book or two, you could own this SUPER easy. It's not rocket science, but you have to be into it.
