I would suggest calling a local TV station and see if they wanted to do
a "human interest" story on you.  Usually there are special reporters
at each station that do the "feel good, local neighbor" stuff.

You have a unique profession and they will be interested.   Explain
to them what you need and they will almost always do a little extra
filming for you and sometimes will give you the original tape!  Have
plenty of refreshing beverage and snacks for the cameraman.

By the way, I would love to see the tape when you are finished because
I anticipate putting in the Pianomation system in place of a stack.
