Hello, I do lighting and sound at my high school (student). Our school can not really afford to fund new mixers, etc. Everything we have is at least 10 years old, we have some new mics, but they were purchased before I came to this school and are very bad quality. We are trying to apply for some grants from local foundations, but if that does not work out, how would we go around asking companies for sponsorships? Sorry if this is the wrong section.
