So realistic steps to look at:
1) create a family trust to own all of your
land,cars, important assets (this keeps people from suing you and getting everything you own or are paying for). Legalees is a great resource for asset protection info (ask for the free DVD he did if its not on Youtube).
2) Start a non-profit. Takes incorporation to get 501c3, unless you are a church/religious/spiritual organization (churches are automatically 501c3 at their start).
Rent your family trust land to the 501c3, you are hired as the director/spiritual leader, kids can have their own company that rents garden and farm equipment to the 501c3 - thier money goes into a college savings account and might be tied to a dollar match program in your area, all tax free. The 501c3 owns nothing, it rents it all from your family and friends - buildings, land, vehicle, tools, office and computer equipment, EVERYTHING.
You have to have a 501c3 to get most of the grant funding out there, except for USDA ag grants, and then you have to follow all of the guidelins and reporting that they require. But the funding will allow you to build, buy, hire, and offer need based scholarships to help fund trainings and classes that you want to offer the coomunity. You can also offer work swaps so people are invested in their own learning while building community.
Remember that if you give it to them for free, you impoverish their soul and make them feel indebted to you, which leads to resentment and a poverty/victim mentality.
Instead, offer them ways to learn, grow, and become proud of what they are doing so that they can teach the same to others and build a stronger community, that leads to a brighter future for all.
Good luck
