I use these guys almost daily.
http://www.freightquote.com/ A lot of difference in the rate is what what classification it moves under. If I'm not sure, I call them. Shipping to a residence or using a lift gate. is expensive. If you know of someone who has a business with either a dock or a forklift, have it shipped there. Or have it shipped to a local freight terminal. My trucking company, which has nothing to do with my gasoline business, now hauls almost all dry bulk, but when we still pulled flats, we moved a lot of partials for people. Many of the partials we met the receiver in a Walmart parking lot and shoved the stuff from the flat to the buyer's pickup.
