I have a on hold project called Who is Blocked. It listens to webhooks (GitHub so far) and try to guess which folks are blocked on their tasks so you can support them.
Im not sure they hire or anything but freecodecamp changed my life for the better and I think they also helped a lot of people out there, some of them are friends of mine.
What's your policy on same account with multiple users (like Netflix)? Usually I split those things with friends so services like this can become quite affordable in our currency (BRL).
Worth mentioning Brazil has new transfer method called Pix that takes mostly 10 seconds to exchange money to another bank account and you only need the other person/company ID or email or phone number or a random key (the account owner choose which ones they want to allow). It came just a few years ago but basically everyone has it now since it's a payment method directly coming from the Central Bank and all banks implemented it by now. It's pretty easy to generate a QR code and bill someone but you can also set it up on your website in a way that you can check when it's paid programatically. Worth mentioning: it's free of costs except if you're a company that want to use the REST API. By the way, they even use GitHub to discuss things and document their API, really nice
