I had someone reach out on a freelancing site some months back for an account I don't monitor much anymore. They had asked my interest about something I didn't find interesting and their budget wouldn't have covered setting up a test system for the issue. That said, I have had people reach out with a project I am interested in (and had time) and did so for the equivalent of low fixed amount. It is rare. I consider them the equivalent of bug bounties.
