We will help you as much as we are able.
Chris and I started small: the first year we did about 95% of the gardening, fence-building etc. ourselves. The second year is when we began bringing in more volunteer help. Don't know if your project will follow the same pattern but don't be discouraged if you have a small group involved at first. If everyone is aligned and committed you will probably get more done than if you have a large, loose group of people who aren't fully on-board.
You will want to find a local non-profit agency to be your "fiscal agent". This means you can apply for grants through them. They will then distribute the grant monies to you as you provide receipts for your spending. If you write a grant that includes a stipend for you and other coordinators, it is possible to be compensated somewhat for your time.
I would encourage you to find a site to begin developing (as you said...). Then you'll be ready for planting next spring. You might also wish to start a Blog or Facebook fan page so you can document your experience and keep others informed.
Be of good cheer! Keep us posted on your progress.
Llyn (and Chris)
