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
It's not bad, however I wouldn't expect the world from it: the kind of things that get bounties put on them are often not $150 bugs - i.e. it's not always the incentive you might imagine it to be.
The bounties do however work as a statement of intent for new contributors to see what is important vs nice to have.
I also would let the bounties be set by users rather than centrally.
We also maintain a fund ourselves with enough money to fund a few things ourselves, our so-called HR fund, I recommend doing that also.
https://issuehunt.io/ - 10% issuehunt fee - 3.5% stripe fee to deposit also 3.5% to withdraw - search seems good with filters - diverse projects - last tweet in 2019
https://www.bountysource.com/ - 10% withdrawal fee - search seems limited - seems to be almost exclusive to crypto - twitter is active
I'm sure you can talk to them then, and figure out the best strategy to offer paid rewards.
