Crowd funding may offer the best bet to mobilize support and raise money. There are many new platforms besides Kickstarter and Indiegogo.
Mini-grants ranging between a few hundred dollars to several thousand dollars are available for youth-driven initiatives.
Make sure you approach state and national organizations that are pursuing similar advocacy campaigns. For example, if you are leading an effort to reduce racism, ask around at Department of Education, NAACP, religious organizations, community foundations–even Teaching Tolerance magazine.
Sometimes you can get lucky getting donations as a result of news coverage. One group of teens had a short article in the weekly community newspaper about their campaign to create a youth center and one reader sent the group $40,000. Publicity also increases your credibility which is helpful in seeking grants and here are a few leads.
Also remember to consider Kickstarter and other online crowd funding sites.
