Can anyone help me find some flute sheet music from Memoirs of a Geisha?

I have been looking and I really liked a lot of the scores and solos in the movie Memoirs of a Geisha. It was actually done by John Williams and I would really like to find some FREE sheet music that has been adapted for the flute. If anyone could help me I would much appreciate it. I don't know how to alter piano sheet music to make it playable on the flute. I realize this is possible and there is probably a technical term for doing so, but I don't know it. I'm quite the amateur.
