It is probably late since I just saw your post, and its a week old, but Cleveland has one main Rental house and thats Cleveland Camera Rental
( Cleveland Camera Rental) ... I used them before, their cool. They also have a camera store Dodd that rents out gear but they are more expensive. I herd there used to be some people with grip trucks in the area, but not so much anymore, although i can't say for 100 percent sure. There are plenty of AC/gaffers to with/ and without gear around though, I know of some if you want send me message and I'll forward your email to them. I just finished film school myself recently, so I am somewhat new, I been on a couple things though. My StaffMeUp is in my info, if the positions is still available. Thanks, Alex.s.
