I used to film theatre shows and dance recitals for money… those parents love to buy copies, even if they filmed it themselves. Another smaller gig is piano recitals/band concerts: if your camera has good enough audio, you can also offer a CD with the video.
I had a hard time at first breaking in to some of the schools and theatre troops, but I started offering to sell the DVDs for $15, $3-5 of it going to the organization itself (as a fund raiser) and I couldn’t stop the jobs from coming in!
