Have you contacted a piano dealer? It's possible it has some value, and
they would arrange transport.
Pianos have no value at all, unless of course you're looking to buy one :-)
I had reason to consider selling a Bechstein grand for someone recently. I
happen to know it's in perfect condition but dealers wanted to "take it off
my hands" and the auctioneer said it might fetch £200. In the end it went on
extended loan to the local schools' music and drama centre.
