Develop usb 3.0 to fiber adapter

Need a board/electronics developed to mux up to 8 usb3.0 devices (cameras in this case, running about 3Gbs each) to multiple fibers and a board to de-mux the fiber back to 8 usb3.0 connections. Budget is higher than what is stated on the project request, I just have it set low so that possible candidates will put an actual estimate rather then what I put in.
