Sponsors can provide valuable financial support to bands, by funding tours and providing new equipment. In addition, many new bands are able to gain wider exposure with the help of their sponsors. If you want to obtain a sponsorship for your project, you will need to prepare and do some leg work. The harder you work--and the more professional you are in your approach--the more money you will gain through sponsorships.
Write an introductory letter to select companies that you think are a good fit for your band. State what you are prepared to offer them. For example, if you're willing to have an official tour sponsor, complete with banner space at concerts, say so. Finish the letter by asking them to contact you for a full presentation.
Do market research. Think about your demographic, in terms of age, location and gender. If you attract mainly 16-year-old males to your gigs, then this will form a crucial part of your advertising research. Listen to the radio stations that play your music or style of music. Make a note of the companies who advertise on those stations. These companies may be trying to reach the same demographic you attract at your shows, reach out to them with an introductory letter.
Prepare a presentation that you can deliver to companies who respond to your introductory letter. The presentation should list explicitly what you are offering, what you hope to achieve in the next six months to one year, the results of your market research, and the amount or type of support you're seeking. After you have delivered this presentation, you have to wait for companies to agree to sponsorship.
Deliver on your promises to the sponsors in order to maintain your relationship. If you fail to deliver on what you have promised, they will not renew their sponsorship. By sticking to the deal, you can retain their support for many years.
