You could ask rich people in your area. Offer your projected surplus of fruit, vegetable, herb, eggs, etc. to the person you're asking for money, or as a small,
local food service for the poor, the needy, the community, etc. that the funding can help generate.
I've often thought about funding issues.
Permaculture could sweep over whole towns, cities, counties, states, with the proper funding. I think of Ralph Nader's "Only the Super Rich can Save Us" wherein the super rich form a super hero type group and fund critical education, fair elections, open media, and the like, to effect real change in America.
A very small philanthropic gesture from the super rich could put 500
permaculture people to work for a year at a time. Creating potentially great change, raising awareness and future safegaurding from myopic agricultural practices and subsidies.
But your
project might just take some asking about town, and some creative community benefits to make it appealing and affordable to fund.
You could also try Kickstarter, though so far I've had no luck with my
permaculture project being accepted. Doesn't mean you wont though:)
Keep me posted.
