This is Steve Wishnevsky
If you can draw it, he can probably build it.
"I have been making musical instruments for over 40 years, and have been doing business as wishbass since 2001. I am approaching 3,000 basses built and sold. I sell mostly through eBay, but custom orders are welcome. I prefer domestic woods, and emphasize ergonomics and sound more than perfection of finish. Most of all, I know how much musicians make, and charge accordingly."
