Animal Welfare Professionals

Hello all!  I'm planning my rescue's first fundraising dinner and silent auction. I wanted to get everyon'e thoughts on the best (and more importantly affordable) hosting platforms for the silent auction piece. We want to open it to more than just the supporters that will be at the dinner.  Our goal is to raise $2k so something that only charges a % of sales would be ideal. 

We use Bidpal, however there is an up front fee.  We have found that it has dramatically increase our auctions.
