Why did I not read this earlier?
Really,this type of idea works with outdoorsy,independent,survival oriented people the best
Sounds like me.
Anyway, I would definitely help out with something like this.
I would be perfectly willing to perform the manual labour required to erect a few structures, not alone, obviously.
Here're a few o' my thoughts:
We live in or near enough to a city to offer cheap and friendly electronic help, like repairs and such.
The televised commune idea suggested earlier may also work out well.
Create a website hosting members' webcomics, podcasts, whatever, and video clips of crazy stuff that happens has great potential for profit.
If we produce more energy than we use (ha!) we can also make a profit.
I'm an advocate of bicycle style generators.
Produce electricity and get your daily exercise.
A farm would also be useful, however, I feel fruits are a better choice than vegetables, so we'd need to be able to grow them.
I'm an advocate of an outdoor area, maybe with a roof over it, for eating/DnD/whatever.
The dorms could be built as a sort of windblock to keep all your character sheets from blowing away.
Maintenance could be done on a volunteer basis.
I'm sure some people will be willing to help.
I know I wouldn't mind mopping the bathrooms.
I wouldn't be cleaning toilets though.
Alternatively, if money ends up not being much of an issue, we could always hire janitors.
New buildings could be added on an as wanted, if money basis.
