uShip (as long as you're not looking for carriers to bring something into Canada) worked well. I found that I got quite a few bids when I changed the destination to Detroit.
It was a bit of a logistical endeavor to coordinate dropoff, storage, and pickup but it worked out in the end.
Shipping companies are always so hard to find and difficult to obtain pricing information from.
It's nice that uShip takes care of the tedious process of searching for quotes automatically and identifies these companies that I would otherwise never find.
