I try not to sell things for fundraisers. We're a drama club and entertain, so I create events that charge admission to the general public and use those as my fundraiser. I also sell advertisment space within our play bulletin.
Some examples of entertainment fundraisers I have done in the past:
Haunted Walk (last two weekends of October). We found a tree farm that was willing to let us use their property for our "walk". We marked a path roughly 1 mile in length, lit it with midgit lights run from 5 different generators (club members donated the use of theirs). Evenly spaced throughout the walk were little skits that the kids created, directed,
etc... that were spooky (and yet kid friendly). One skit that was great was a parent who wore a white sweatsuit and wrapped herself with 2" wide white strips she made from an old bed sheet. She just prowled the path as a stage mummy. We made $2,000.00 per year on it and it was fun. We could have made more if we were allowed to sell food (we were thinking on donuts and hot cider).
"Grand Valley Idol". Think of the TV Show... charge $5.00 per person (and $10.00 per act). Get three area celebrities (I got a local church choir director and radio show host) for judges and have fun. Let the audience vote (I let our school's special singing group entertain the audience while the votes were counted). Prizes can be given to the winner. The prizes can be donated too!
A Night of One Acts... We have an ice cream sundae bar that people can create their own sundae for $3.00 (get the stuff donated for the sundaes), charge a $2.00 admission and perform 2 - 3 one acts while they munch their ice cream. We make about $1000.00 on it.
Car Wash. Or "topless car wash" (can't do with high school because of the implications of impropriety). Wash only the front, back and sides of the car (we do ours by donation). The top is extra! We make about $750.00 and it is fun! We could have made more, but there were two other ones within 400 feet of us).
I'll list more later... I am a bit rushed for time.
Good luck!
