Local Businesses Invite local businesses to be sponsors or supporters of your group or project. In return they could have a letter of appreciation from your group that they can put up on their wall. More substantial support can be acknowledged in other ways, such as mention in media coverage. A good way to find local businesses that tend to support causes like yours is through the Chamber of Commerce. If you know the owners at all, that could be a big help.
Many corporations give away a portion of their profits to good causes.
Sometimes they'll donate their products, as well. You can get a corporation's address from the back of their product labels. Just go into a market and write down the addresses of any company that you'd like to see support your project. Call the company and ask to speak to someone in charge of donations. Tell this person about your project or organization, and invite them to contribute.
