This is something I developed for client who has since disappeared,
https://bitagora.co its basically a copy of thebigcoin.io if you haven't heard of it it allows users to enter a url of something they want and pay for it with crypto while you the operator takes a fee and buys the item with a credit card. the sale includes a couple hours of my time so that I can show you how it works its written in django and react, you'll need a coinbase account to accept the crypto payments. there's a nice admin view on the backend as well. licensing is optional.
