I don't have children, but I well remember the MS readathons and the Thin Mints and the boxes of chocolate bars. And I hated every minute of it.
For the fun of it, I googled "school fundraiser" and stuff like "grass-fed" or "trail mix" or "fair trade" and got lots of stuff:
School fundraiser for delivery of organic produce Organic Food | School Fundraising | Natures Garden Delivered <-- looks to be based in Arizona, but if you're really enthusiastic maybe you could look into something similar.
Here's an even better one in Arizona -- grass fed beef and organic chicken. https://www.toplinefoods.com/2011/09...sh-to-schools/ <-- this one looks kinda weird though, might need to do research
Here's a farm-to-table fundraiser, based in Wisconsin: School Fundraiser - Farm to School - REAP (Research, Education, Action, and Policy on) Food Group
School fundraiser for nuts and trail mixes: Nut & Trail Mix Fundraising - A Healthy Alternative Fundraiser <-- Plus many more if you google "school fundraiser trail mix." It's not entirely primal, but come on, they're kids. And this might be the most acceptable to the other non-primal parents in school.
Fair Trade fundraiser ideas: Equal Exchange - Fair Trade, Green School Fundraising <-- lots of vegan oopsie stuff, but also gluten-free and good chocolate and coffee.
And if you don't want to sell food, even LunchBots -- the folks who make stainless steel lunch containers -- have a fundraiser program: school and group orders | LunchBots Stainless Steel Food Containers
5'0" female, 44 years old. Started Primal October 31, 2011, at a skinny fat 111.5 lbs. Low weight: 99.5 lb on a fast. Gained to 109 on sugar cheat. Reset with 85P / 90C / 90F. Currently weaning off fat to 85P / 90C / 60F.
MY PRIMAL: I (try to) follow by-the-book primal as advocated by Mark Sisson, except for whey powder and a bit of cream. I advocate a two-month strict adjustment for newbies. But everybody is different and other need to tweak Primal to their own needs.
