If you want your event to get attention or have a special feel, add a sky dancer- it's good for events such as a sale, fundraising, school or any big event. You can provide your own banner of 4 ft tall x 8 ft wide but if you want us to provide one, please ask for assistance as there is an additional charge of $150 for that. Additional $300.00 premium for setup if needs to be at a roof top. Rock Rental charges 5% for credit card payments, no additional charge if paid by cash or check. Rock Rental's delivery fee is based on $2.00 per mile round trip without a trailer and the travel fee for 1 vehicle towing a trailer is $2.50 per mile one round trip from El Cajon with a zip code of 92021. If the location does not have a power source within 100 feet of the back of the unit, you will need to add a generator to your reservation.
