Community Volunteer Sound Engineer

I am a sound engineer that volunteer's for several community events to run sound, mainly for charity events, I had been able to borrow the equipment untill a few weeks ago but have been told that they would no longer be able to loan out the sound equipment. I would love to be able to continue to volunteer to do the sound for events but I just don't have the money to purchase the entire system, I have purchased the sound board and the main wireing but I still need around $800 to purchase the rest of the equipment. I apreciate anything you could give to make this happen.
