Transcribe a short tune and compose an accompaniment for it.

I'm attaching an mp3 of a girl singing a tune. I need you to transcribe that tune into a Sibelius file (or NWC) and midi. Please, I need it absolutely based on the mp3 I attach. I know that the girl changes the tempo and the tones a bit. Use your judgment to normalize that. And I need you to compose music to accompany that tune: Something jazzy, something swingy, in that mood. I think about something with Piano, Drums Kit (hi-hat, you know), bass, and maybe sax. When ready, please send me a link where I can listen to what you've composed.
