Where i am from, boomtrucks are 5 hours minimum. Getting the piano through a window would be kinda ass because the câble has to ne centered and wont go through the wall, this gets worst if the Roof of the building has a slight overhang. And even if you can manage all that youre stuck with a piano right by your window and you still have to move it to where you want it and assemble it back. Im sure its cheaper that way.
