If you make a list of local business to contact and have a letter ready, you can split up local businesses among your group. Sometimes businesses have online forms, so Google donation request and business name.
Also, you can work together to constantly make money based on your purchases (affiliate commissions) - you do this by using the same link to Amazon, Overstock, and other companies.
