What's the best way to start an online Charity Auction?

Question by Abigail Lee: What's the best way to start an online Charity Auction?
There's a couple in our town who are in bad financial trouble and I want to help them. I thought that an online charity auction would be a great way to do this, except that I have nothing to sell. I think that it would be awesome if I could get 120,000 people to give $ 1 each, who'd miss a dollar? And that would be the way to get donations. Maybe an auction isn't a good idea? If not, how would I go about
