I live downtown in a fairly large city directly across the street from a medium-sized college campus. I literally see both kids and adults walking around campus right now through my window. In fact, I can look through the windows of the building across the street and see kids in class. I've tried handing out flyers with QR codes or website addresses with affiliate links, but those didn't even earn a dime. I'm curious if anybody has any tips or ideas on how to make money off these kids -- and lots of adults returning to school, as well. Once I can generate a successful idea, scaling up would be essentially easy due to all the kids looking for jobs nearby.
