I want to invest in Social Business for christmas

My extended family is beginning to ask the standard christmas question: What do you want for a present?  I'm having difficulty thinking of a gaudy trinket to ask for, so I've decided to ask for a donation to a worthy cause.

We saw Muhammad Yunus On Andrew Denton's Elders show the other night, and I was very impressed with his vision for improving the lot of the world's poor.  He makes it seem like solving poverty isn't hard, which makes a great contrast to the things that some people say.  I especially like the concept of a Social Business, whose purpose is to serve the people in a locally logical way rather than turn a profit.  Interestingly, one would invest in a social business with the intention of getting the investment back at some point, although not necessarily with a profit.

So now I'm all fired up, and I'm going to ask people to invest in Social Business instead of buying me presents.  The only problem is I don't know how to let people do that.  I'm going to have to do some research to find out how it can be done.
