I left teaching math because I made more in tips waiting tables, but I often help other servers by doing thorough written “tutorials” of their college math assignments. Is there a way I can independently monetize these?

Here is a link to 3 small examples that I had pictures of on my phone. https://imgur.com/a/PuScwQ7 I’d love to find a way to monetize doing these, even for a small little income to make my masters degree not feel like a waste, but I just simply don’t know how/where to even start. I thought this sub would be a good idea since you guys support a more independent approach to financial stability. Thanks for any advice!
