Hi Joyce and All,  All serious piano and player piano rebuilders have
what's called a piano tilter.  Basically, it's a simple device that
attaches to the back of the piano that allows the user to 'roll' the
piano over onto its back while at the same time raising the piano about
1-1/2 feet off the ground.  In your local area there is most likely
a piano technician/tuner who has one.  I've posted a picture of two
such devices at  http://www.player-care.com/gifs/tilter.jpg
