I would suggest getting in a local club, attend a few get togethers and then see if any of the members want to have a wrenching party. Installing the disco's would take an hour tops, front bumper with a winch probably about the same amount of time with a group who know what they are doing. Provide the pizza and some adult beverages and I bet you will get some volunteers. As for the lockers, that might require giving up some cash to whomever volunteers, that is a bit more work then the rest.
