If you have access to a good, strong leaf blower, buy a large janitorial dustpan or scoop (name differs by region), preferably a sturdy metal one with a replaceable heavy duty vinyl edge strip, and strap the dustpan to your blower's nozzle. There is a commercial, manufactured version called Air Jet Snow Shovel, an add-on leaf blower accessory, if you have the money. It works on ice, too, once you crack and remove an edge of the ice sheet so the blower air can get under it.
