As few and far-between as the CNC machine shops and PCB assemblers are in the west, it's even fewer if you want something even moderately sophisticated for making a high-tech product like stamping, spinning, heat-treating, electroplating, coating, anodizing, rubber-overmolding, photo-etching, screen-printing, and so on. At that point you basically buy machines (probably from China) and do it all in-house, or you send it to China where, as other commenters point out, you'll get an affordable quote back within 24 hours. But once you're having your parts heat-treated by one Chinese company, electroplated by another, and over-molded by a third, you really may as well move the whole production line there.
