Last year I had to have my neighbor do it after one of the blizzards. He rented a skid steer for the week. He charged me $60. Not sure if that was high/low or about right, but the drift I had in my driveway didn't give me a choice. However, he didn't make me sign a damage waiver and he did damage 3 sprinkler heads and tore up my grass. Those were easy fixes for me, so I didn't worry about it, but had he damaged concrete or my house, I would have talked to him about repairing damages.
If you decide to do it, I suggest getting a contract expert to put together a damage waiver for you.
