Is there a product out there that makes it easy for open source maintainers to offer enterprise support services? I think support is probably the best way of making money from open source, but a lot of maintainers are unlikely to have everything set up to do so (business entities, contracts, ways to receive payment, probably a dozen other things that you'd never think of, etc.). Like Stripe Atlas for open source consulting?
