I know you have a for sale/rent a free stuff section, have you given any thought to a Barter section?
I know in this economy, cash is scarce but many have skills, services, products that they would be willing to offer in exchange for other skills, services, products in lieu of cash.
I know that there are web sites out there for bartering, but with the fees you have to pay, well, still cash involved.
What say?
