This is not a fully formed idea yet, but have you tried reaching out to one of one of your neighbors, the VlogBrothers? https://www.youtube.com/watch?v=QhVxNo-HA8g
I have no relation to them, other then I am a fan of their channels and I'd think your missions could align around Permaculture if they learned more about it. https://www.youtube.com/watch?v=-enGOMQgdvg
I'm not sure this specific $5k is the one to bridge you together, but having watched many of their videos, I would love to see them doing one on Permaculture or maybe getting kids into gardening.
Just trying to get you to infect new brains,
