FPGA miner for X11

I am looking for someone who can design a FPGA based X11 miner to mine X11 based coins like DRK. The design should be adaptable for possible changes in the X11 algorithm, and / or for alternatives like X11+1. Examples and working implementation in c++ can be found in multiple project like cpuminer-multi on git. FPGA should be capable of mining with reasonable performance (at least 50 mhs per 1000 usd fpga hardware cost). FPGA code has to have some kind of configuration interface (web, CLI), where details like mining pool, username and password can be set and changed, and where performance values like hash rate, accepted and rejected shares can be monitored. Developer should commit to Non disclosure agreement, and is not allowed to share the code with 3rd parties without written confirmation from the project investor. Developer has to provide 72 hours running proof of solution, then send the end solution, including code base, compiled code, written documentation about how to upload the code to ( by developer specified) FPGA and how to use it, including clear written instructions how to change parameters like username, mining pool and so on. Source code and FPGA translated code is property of the investor, as is also the documentation and all parts of the project after project has been completed. Payment is done 1/4 after 72h proof of working solution is provided. The rest is payed after after project completion, and after shipped components are inspected and put to work for 72h, and no errors are identified. Project costs are ONLY FOR THE SOFTWARE PART, hardware components will be payed separately, or ordered separately by the investor. Thus, the code has to be up loadable to any hardware that matches the developers hardware.
