Ask HN: Garagesale, my weekend project. Can I monetize it?

Last weekend I hacked a project and published (thanks to duostack) at http://garagesale.diotalevi.com

My goals:

- learn node.js/express/jade with mongo

- sell my furniture! since I'm moving to another country

Now what I'm wondering is what you guys think about the product. Could I sell it as a service for other people in the same situation? I couldn't see many similar websites, even if of course one would use eBay for this kind of things.

If that's the case, what are the mandatory features to add to make it a MVP?
