Stephen Schlaks - What are you doing tonight

[ilmatar]

Hi everyone,
I'm looking for the music sheet of the song:

Stephen Schlaks - What are you doing tonight

my girlfriend loves this song, but I cannot find it anywere. I'm a beginner, so I don't know where to search, but I've sent dozen of mails to music stores, artists (to the official author website too, but it has redirected me to a publisher that no longer exists =) without any result.

Do you know any information that can be useful to me? (a music store that I can contact, a website capable to find it, ...).

Thank you for every info you can provide to me,
Francesco Fontana
