Patrick Bowman writes "I'm with a small (okay, it's just me) startup planning a camera-related USB device for the mass market. It's probably patentable so I can't give details. I can handle the software but have no hardware design or manufacturing experience. Does anyone have any recommendations for a company to handle the PCB design and manufacture? Instead of starting from scratch I've also considered approaching one of the companies (mostly in China) that make similar devices and asking them to modify their hardware for my requirements, and to provide their source for me to modify. Has anyone taken this route before? How did it work for you?"
