Here's a site where you can subscribe to find Green Jobs: http://www.greenbusiness.net/green-jobs.html
This great new community has been started by a chap who lived without money for a year, to see if it could be done. It's basically a site (and community) that facilitates skill sharing.
You set up a profile listing what skills (and tools etc.) you have (that you are prepared to share) and people can search for you and ask for help with something. Which you give, for free, and make new friends whilst doing it.
In the same way, when, for example, you want to learn how to bake, or need your car fixing, you search for for people listing baking or car mechanics as one of their skills, and they help you, FOR FREE.
So the system is basically based on the principle of 'one good turn deserves another'.
