Try UShip.com.
Shipping companies use it to find small loads to "fill up" their container or moving van. May be someone on there that would be interested.

You can either solicit bids or set a price you're willing to pay. In that scenario, I'd solicit bids.

I've used UShip 3 times, including getting my mother moved here in 2 weeks. They have user reviews just like ebay and you can read all their feedback from people.
