One thing that I had some minimal success with is reaching out randomly to non profits and asking them if they need any help, say with Word Press or something like that. Non profits are really big on the lower salary stuff and will probably be super grateful that you're able to do anything VS the janky/expensive setup they have currently. The cool thing about this too is you can look up non profits that you support and so it's more personal meaning than fixing some cursed CSS bug on Random Big Tech SAAS startup. I figure you may be able to work part time at a couple of these and have it add up?
Another thing is checking craiglist computer gigs. I've found interesting stuff there, most people don't think to look.
My hours have to be really limited so these options work for me less, but maybe they help you!
