This is basically removalists, yes? The last time I moved house, I paid a removalist to get rid of a bunch of my stuff. Paid them by volume of removed material; they did all the work to take the stuff away. (I basically said "take everything in that room over there"). Took a couple hours, and it was done. They disposed of everything responsibly, and would try to sell things which were reusable or salvageable. The cost to me was dead cheap, because most of their profit (I assume) came from reselling the stuff that could be salvaged.
