Your customer is having an entrepreneurial fantasy, be careful. I drop=20 projects like this, or, require a per-hour for doing the research for=20 showing that this is not possible. I would point him to alibaba and have him do the legwork to find (if=20 possible) the factory that produces the BTLE controlled (whatever) that=20 is similar to what he wants, and have them quote a custom build. You'll never reach even close to china volume prices based on anything=20 non china sourced. Good luck, and don't spend too much unpaid time on this. Your role will=20 be a EE consultant on a china manufacturing QA adventure.
