I currently don't have a concrete opportunity for you but maybe something to consider: I occasionally teach at universities, and students often learn about accessibility as a general topic but have zero insight into what it actually means, as in: how a real person with an actual disability is using assistive software. I sometimes show them YouTube videos of people explaining their screen readers. I am sure that universities could be interested in some kind of package, where they bring you on remotely, perhaps, and you can do a live session of reviewing something students designed, or talk to them about things most apps/websites tend to get wrong (are cookie nags extra annoying/complicated to deal with to you, or do you even stand a chance at unclicking some of those tracking options, how about apps without buttons, mostly controlled by gestures, etc.). As a teacher, I didn't know even where to start reaching out to someone (at the time when I wanted to do something about it) who could actually show students how they "see" (or not see) those websites and apps. Again, I think this is something you should most definitely get paid for (it's super valuable), I didn't have the ability to get a budget at the time, but would have had a much easier internal pitch for it if there was someone already offering this as a package deal kind of thing. Like, a 2 hour call before a project, then students work on it, and you come back in for another 2 hours at the end of class / semester to review.
Anyways, I'm rambling on, but I always felt like this is something that would be valuable and also struggled with connecting the right pieces to make it happen.
If you're into web development, too, or maybe even just Notion could work, would be a potential indie project, too — a "hand-crafted job site / market place" of accessibility services / experts."
