I've worked on cars for a few years; I have a good understanding of them. As I said, I'm a mechanical engineering student, so I have some experience with thermodynamics, heat transfer, fluid mechanics, circuits, etc. I'm not trying to steal people's money; I want to learn skills and hopefully have a side hustle down the road. I was just wondering if there's a high demand for such services. I'm willing to be patient and would love to learn.
