Where might I rent a printer for 5x7 prints for a photobooth?

I am close to getting a contact to shoot a corporate event this October. One of the things they wanted was a photobooth, which isn't a big problem because I've done them before. However, they want 5x7 prints, which will take much too long to print on my equipment. So I am considering renting something which will print faster and print 5x7.

Where would you suggest I contact?


Thanks.
