What would you expect to pay?

We knocked down the old wood shed in our backyard but the roof is too heavy to move in one piece, it needs to be cut up and we don't have a chainsaw. DH has a guy coming over tonight to give an estimate but he already said he is pretty negotiable. I have no idea - basically he needs to cut it into a few pieces and take it out to the curb. Any ideas?
