Donation drive management software?

A friend of mine’s hometown was particularly hard hit by Sandy. Organized relief efforts there appear to be limited and her family & neighbors are asking directly for daily living supplies - clothing, batteries, food, etc.

The friend’s asked me to make a simple website to coordinate what’s been given already and what’s still needed. Are there any web services that can help with this?

I was thinking of just doing it with a Google Spreadsheet or a wiki, but is there a better way?
