Distribute 50 Flyers in SF

I need 50 printed flyers handed out or posted in San Francisco’s commercial zones, with a focus on busy office-building clusters. I’m not tied to any fixed street address—any lively business district that sees regular foot traffic will work, so feel free to map the ideal spots as you go...
