Hey Mike - Great idea, I hope you are getting model releases, just to save you and your business from those that might not like having their photo in a public gallery.
Also, it might help when you (thinking outside the box here . . .) contact the National Archives,Smithsonian, or some other government body that might be interested in purchasing your collection of images to put a human face on a time in US history that is being compared to the Great Depression of the 30's. Think Dorthea Lange!
