I started thinking about how your video could be used to inform state and federal lawmakers, who might then be convinced of the need to target hard-to-reach men to participate in a vaccine trial. They might then provide funds for dissemination of your video to a wider audience. One approach would be to meet with SF Aids Foundation (if you are not already working with them).
"San Francisco AIDS Foundation was the California Statewide Coordinator for AIDSWatch 2014 and held a dozen meetings with key congressional offices for the state’s participants. “Despite the very tight schedule and rainy day, the participants were successful in conveying to policymakers the importance of federal HIV/AIDS programs to Californians,” says Hopkins."
