Well, if you are good at something, try making some professional grade tutorials on Udemy or Gumroad. It’s not likely that you will become a millionaire over night, but if the content is good you may be able to start making some side income to help pay for freelance work.
@ZacD is certainly right though. It doesn’t hurt to offer royalty based work to people, but most are going to stay away. If they aren’t getting paid, freelancers want to work on their own stuff. So I would strongly suggest tutorials, especially seeing as you aren’t artistically inclined, that makes the options of publishing 3D assets to an online marketplace less viable.
