Dave's got the plan, and Pops suggestions are what I follow with the engine stand thing.

The other alternative? When I was MUCH younger one of the things I did to make a few extra bucks was move pianos. My partner in this operation was about the same size as me, say 6', 175#. Most moves went smooth because we didn't fight each other, teamwork is always better. On those rare occasions where we had to move one out of a basement we'd get one of my pards employees to help. He wore a size 3 hat and 54 coat......we put him at the bottom.
