How much to sandblast a bed?

[RPBurris]

So I did a search on the forum and could not find any recent posts regarding sandblasting costs. I found a place close by me (think NW Indiana/Chicago area) that would blast my 8' bed for $600. It was just an over the phone ball park but from what i have seen it sounds high. Does anyone know of any other sandblasters in the area? The guy i called is highly recommended and does high quality work for custom car builders in the area. Thanks.
