Teachers are so busy that they need something that will earn money in the background, without them having to manage lists, signup sheets, checks, envelopes, etc. One option to consider is a logo apparel website. There is one called
www.logoprideapparel.com that is completely free, offers a variety of clothing items with delivery to the home, and pays a fundraising incentive of $2 per item sold. Parents can order year-round, and you could designate all the proceeds to go to the teachers. For 960 students x 4 items per year (per family) would be almost $8000 that you could divide between your teachers for supplies or as a gift. I have ordered from this site before, and I liked the variety of golf shirt styles and colors - a shirt I actually enjoy wearing.
