Hi,
I can design the system for you and I am better suited for it. Though an expert in embedded system and interfacing them with PC, I have worked in an ASIC-design company for quite some time. With experience in ASIC/FPGA, I worked with bitcoin community for developing open-source fpga design for bitcoin mining, and left only when MT Gox had their first security breach. Contact me if you like the profile.
PS: Refrences can be provided if needed.
Regards,
Azhar Sultan
