As a fundraiser for my FFA chapter, we do a livestock and horse judging clinic every January. We get everything sponsored by local businesses so that all the money we bring in is a profit. Also, I like to use my students SAE projects as livestock (one of my students' raises market steers, so we are using and advertising his steers for sale) because it gives the kids recognition in addition to seeing how well they breed their stock. All of the livestock and horses are from local farmers and ranchers and so it really shows what our community has/does, especially since we are in a small, super rural area.
If any of you are looking for fundraisers, this is a great one. I've included all sorts of documents that could really benefit your teams as well. Use what you want.
