It depends on the local situation. I don't know if the band, singer and costume are made by myself or find a professional. Professional fees are different. (sorry. Besides, there is a lot of flexibility here. I hope my friends had better find someone from school or something. If they are professionals, they are not cheap. )

3. Find a wedding (personally, the price is favorable) and rent a table, lighting and stereo. It depends on the scale. (considering the small size, it is probably 1500~8000, and there are more expensive ones. . . )

4. On-site maintenance personnel. In order to reduce costs, ask your best friend for help.

If you don't mind, you can try to find sponsorship, which may help you relieve a lot of stress.
