Renting a dyno?

[Powerstroke92]

I was wondering if yall could give me some info to find out if this is feasible. I am an officer for my Universities Ag Systems Management club and thought that setting up some sort of a dyno day would be an awesome way to have a fund raiser/ attract new members and future students. Could someone give me some info on who rents mobile dynos near the midwest and what something like that would cost. Thanks
