Rock Rental, LLC charges $37.50 per operating hour per staff for jobs within 40 miles of our address. Anything beyond 40 miles will have additional time charged for the extra staff to travel to your event. Everything we rent must have adult supervision when our equipment is set up and ready to use. The large items like the rock walls, trampolines, and mechanical bulls come with adult staff. However, just about everything else does not. The customer is required to provide adult supervision for each piece of the equipment. No supervision means the equipment must not be used. We encourage our customers to provide reliable and mature volunteers so that they may save money.
