You'd likely do better (and get to it a lot sooner) if you look for a MIDI file of the targeted songs. Still, that won't likely deliver up a piano sheet music chart.

There may be published sheet music for Piano out there on your songs, that is another way to go, but of course the instantaneous key change won't be there for you.

If your teacher expects to see a printed sheet chart for piano accompaniment, you should bite the bullet and purchase same even if you have to end up picking other songs.
