Dev board project to a real product

Hi,

I am coming from software side and have no experience on  converting a dev board project to a real end-user product.

Say that I have developed the software on Edison, and the project requires  6 relays(3.3V and level-shifters?)  and antenna.

From this stage, I think I have to search external board designer/builder services companies? Can you or (Intel) suggest such companies, perhaps experienced on Edison chip? Is Edison chip ready for real products (legally)?

Thanks

Bora
