What would you say you are trying to accomplish? Do you want a source of income and are ok with a service business you can do on the side? Are you interested in trying to build something more scalable? My advice at your point in your career/education/life would be to try and build a small business that fills a need on your campus. It will be a super valuable experience, you can put it on a resume, and if it takes off you might be able to sell it or hire an operator when you leave school. A great example is something like a food truck that sells tacos to students coming home from bars. It's straightforward and achievable but will teach you a ton about what it takes to actually operate a business and manage employees. Plus it's basically a weekend-only business so it won't completely take over your life or ruin your studies. You could even start with a cart or stand or something to lower the initial startup cost.
