We thought about offering bounties and then letting users write invoices to our open collective so they can get paid.

The questions would be:

1) Is offering bounties even worth it? 2) What range should a bounty be? min. 50$? 3) Write an invoice and get 100% of the money or use a system? 4) What systems are out there and which one would you recommend?

The Open Source projects we are considering it for is: https://github.com/open-wc/open-wc https://github.com/modernweb-dev/web
