This is absolutely awesome. Sounds like a really great way to make the world a better place.

Not everybody is using fb, I hope you'll finish your http://garagescript.org/ website soon because now most links don't seem to be working. When you provide more details I think you may find some people who are willing to donate. E.g. is non-profit registered under garagescript? I couldn't find it. Well at least make contact and linkedin links working now that you are going to get some exposure from HN frontpage.

Got a bit too much into details, but what I meant to say, really great initiative, kudos.
