There should be some money. The copy shop next to our school has changed from one to four now. It only took three years, and the market is still quite big. It's a good habit to enjoy college students' information, especially at the end of the term, when the print shop is full, there will be something to copy and print at ordinary times. If you are alone, the prospect is very good.

Moreover, you'd better have a long-term cooperation project with the student union and class, so that they can go to your place to do printed materials and settle accounts every month or at the end of each period, so as to save trouble, retain customers and stabilize business.

In fact, student unions and clubs are the markets you need to explore most. How many activities do students' unions and societies hold every year? The cost of publicity alone is tens of thousands. You must use banners and posters for publicity. How much does it cost to copy a piece of paper? What's more, students take money from school. When it comes to copying, it is hundreds of copies, much more than three or five copies printed by ordinary students.

I hope it helps you.
