Tourism Site for Volunteers and Activists

There is a need for a web business that plans Social Activism, Volunteer, and Relief group events and packages them as vacation plans. People could sign up for the event, whether it be Haitian Earthquake relief, Gulf Coast Oil Spill Relief, or other event. The trip might include lodging, travel, a work schedule, food, etc. The trips might cost money, be free, or pay money depending on the cause and funding.
