The following is my opinion on the basketball club.
I don't think your "basketball hut" should be too fancy. It is good to decorate it properly, because this is a sports-oriented club, and its main energy should be practice.
I don't know which city you are from, and what is the atmosphere of high school basketball there. Since we want to sponsor, the first thing is to have a fixed competition time and a fixed occasion to arrange advertisements for sponsors. If we can form a small league with other schools nearby and organize competitions at a fixed time, and the schools agree to advertise on campus, I think the owners of sporting goods, student restaurants and stationery stores should give some sponsorship.
In fact, the competition doesn't need to be too frequent, and once or twice a semester should be an acceptable frequency.
However, if the competition is only held on campus, it will inevitably affect the attention of sponsors because of the small scale of the competition. At this time, it is necessary to provide a high-intensity advertisement to promote sponsors on campus.
The most important thing for the rise and fall of a community is not its achievements, but the attitude and confidence of all its members. The internal backbone must set an example, but it should not be rushed. No community can rise in a short time.
The above is my personal opinion, I hope it will help you. Because I am in a hurry to eat, language organization is not suitable. Please forgive me. I am a college student and the head of the school sports department. I hope my experience can help you. My QQ number is 176 10632.
