what kind of rock is it that someone would want to polish it? Generally the stone goes to a hole that needs filled in.

i dont know how it works. its a giant stone (like 25' x 20' x 12') it looks like stone you could make a wall or something.

If you can line up someone to haul it away as soon as it's ready you may save a couple bucks on disposal with your contractor but I wouldn't get my hopes up on offsetting the cost by much. Around here if stone's not strapped and palletized it better be free, or close to it.
