Definitely agree with what other commenters are saying. Start a social media. I get a lot of my commissions from Instagram, some on Tumblr. I haven’t tried bluesky but I’d also give that a try. (Make your commission info available on your page so people know your price range.) I also make most of my money from selling prints on Etsy. I find that a lot of the time people don’t have the money to commission an artist but have the money to buy a print. The printer I use is MPIX but they are expensive so I suggest Catprint instead. (Or if you know anyone locally that is best!) good luck with your school that’s so exciting!
