My wife and I are opening up a new Studio Share in our area (www.studiosharem.com). We're planning on hosting regular workshops, and we'll be seeing a lot of photographers all the time. I've contacted a few different places about sponsorship, and they've indicated they're interested, which is awesome! Now the hard part is how to set up the sponsorships. Do you guys have any experience with this kind of thing? How much are sponsorships usually set up for? Suggestions on whether the sponsorship should be per workshop or just a flat rate per month, or maybe neither one of those options?
