What is the cost of the music materials of the show “Berlín to Broadway”?

Hello:

I am trying to organise an evening concert in Spain with music of Kurt Weill. I have seen a reduced orchestration is used in this show, and that's the point of my interest.

I would like to know the kind of availibility of this music materials, and its economic conditions.

Thanks for your kind attention and for your answer in advance. (rubenmenendez@gmail.com)
