How much should I get paid to snowblow a driveway?

I live above my place of work, and the landlord has asked us how much we would charge to do the snowblowing ourselves. It's a driveway that goes along the side of the house with parking for two cars in the back. They are providing the snowblower, we would buy the gas. I have no idea what going rates would be, most ads are for plowing, not snowblowing, which is obviously more work. Thoughts? We live in upstate New York.
