I doubt it...basically, all you'd be doing is buying parts from someplace like Warmoth and slapping them together. While some people will pay a tech to build a parts guitar for them, the type of person who goes the custom route is usually the type of person who is competent enough to assemble and set it up themselves. I really don't think there's any money in it. Even if someone did need the services of a tech to put a parts guitar together, they'd likely seek out a professional instead of a hobbyist.
