I've been planning to order a custom work but I don't know if @Brivium can do it. The market place is just like a normal resources display where users uploads their (Dlls (GameHack)). Just like buying add-ons. It has expiration/usage limit. This project contains c++ application where clients are allowed to use the application and with some kind of "keys" that generated when client bought the resources. I have total $500 budget. PM me when you're interested.
