This is a great idea! I would love to help out with development (I do full stack development). I think Utopian would be a good way to subsidize this as well. I actually think it is much better than local bitcoins because:

1. Steem transfers are instant
2. Steem has no transaction fees

• This means you do not have to wait 30 minutes+ for the confirmations with the customer
• If someone is uncomfortable transacting a large amount of money, they can do it in multiple small amounts

Wonderful idea! Lets move fast!
