Jen,

Definitely get the media involved. Call the TV stations and newspapers. Tell them the plight of the organization.

Yard sales are a great way to raise funds. Don't forget, "One Man's Junk is Another Man's Treasure". I'm sure there are LOTS of people, both volunteers AND people who have adopted from the shelter that have "stuff" they're willing to donate for the sale. All it takes is a phone call.

Good luck.
