Hi, This sounds like a project I am genuinely interested in! I've done similar smart contracts before, so it wouldn't be that big of a deal for me. A little bit of background: I'm a solid backend engineer with blockchain experience an interests, familiar with smart contracts, Hyperledger and bunch of other blockchain technologies. In any case, I'll be more than happy to discuss this project with you in more detail. Best, Vladislav
