I ship 650 lb. items weekly. I use Freightcenter.com It's the easiest and best price I have found. Just type in your dimensions and weight and it will give you a dozen or so freight companys to choose from. I have had the best service with Roadrunner or Central, they will probably be one of the choices. If you can pick it up at your local terminal you will get the best price. Also see if your seller can drop it at his terminal. Terminal to terminal is the cheapest way to go. Hope this helps.
