I used 1800GOTJUNK.
They would not give a quote. They based their pricing off of the cubic footage of the truck and how much space my crap took up. At least that's how they did it when I used them a few years ago. And like Raven117 said in post #2, they are not cheap. I think I paid $400 for them to remove one couch and one chair. Now mind you, the guys who showed up were very polite, respectful, and professional. They broke down the couch with their own tools since it wouldn't fit through the door. They cleaned up the mess without being asked. It was a fairly fast and friendly service call, all things told. But they are indeed pricey depending on your budget.
