That is, apply to the student union for sponsors to pull banners, and then you can put the sponsors' names behind the uniforms of the sponsored teams. They mainly provide team uniforms, mineral water or functional drinks, coupons, and best of all, shoes and cash.
I believe that smart businesses will not miss such a good opportunity to promote their own brands. What you need to do is simple. Contact some small restaurants, sporting goods stores, sporting goods stores, even hair salons and karaoke shops that do student business, and tell them that the college will hold a basketball match. I hope they can become friendly sponsors, and give some promises to attract them, such as where to pull the banner and where to type the name, but the corresponding banner is the price of the banner, and typing the sponsor's name is another price, if both parties are willing.
