Media Production Class

My school's administration has given me permission to pursue a media/video production class at my school. Any suggestions on how to fund such a program? Video production and editing equipment can be expensive. Does Disney or Nielson have a reason to fund a program at an Orange County high school? Anyway - I'm open to any suggestions you might have. Right now my main funding idea is the annual production of a video yearbook for the school. The question is - how do I get the equipment to make the first one to sell.
