My hobby photography business, which my wife and I run on a "pay what you want" model, brings more than enough to pay our monthly bills and have some leftovers for savings. While the last time I checked about 97% of photo shoots paid below average, the 3% that paid above average more than made up for it.
We also donate part of the profit of every photo shoot to a non-profit that helps women fight breast cancer, which aside from the good feeling that it give us, also helps with marketing on its own.
It is an interesting business model which not many people take advantage of, and may be perfect for Counter.dev for sure.
