How can I demonstrate value to a sponsor when I'm just starting out with limited resources?

Start with product sponsorships and dramatically over-deliver on promotion. One successful example: two young girls wanting junior dragster sponsorship asked to sponsor a local burnout contest for just $500. They put up banners everywhere, got the announcer talking about the brand constantly, and sent back turnkey videos of the event. This creative, low-budget activation impressed the sponsor so much they moved into a full dollar sponsorship for junior dragsters. The key is doing something different in your local community that creates real visibility and shows initiative.
