I have a x0x kit from 2006, I think it's from the fifth run. Anyhoo, 6 years later I have a partially built x0x. It's a quarter built by a military electronics engineer. So I believe whatever's on there is really solid, professional work and it shouldn't require any attention. I live around the NYC area but obviously can ship to the world. I'd prefer to find someone with some experience x0x building (finding the best position for the resistors so it's most closely specced to a 303, etc.)
How much? How long to build? Hit me up!
