Need 1 song reproduced

I need to be reproduce it as it is but in a lower key (-2 or -3). I'm going to sing and then I need it to be pre-mixed. Genre is indie pop. It should be 2 min. Deadline is April 20th. I haven't sheet music or chords or something like that. I prefer virtual instruments. I'm music student in Turkey and my demo is going to listen by one of the most important producers in Turkey.

Additional info:
I will be recording vocals on my own. I'm an indie artist. I need it delivered by DATE. Check out what I attached. I'd like you to also mix and master if possible. I'm looking to hire a very experienced producer. I'm looking for someone to re-record a demo I've already created, but with high-quality samples, synths, and effects. I need someone to help with the entire song-making process - writing, arrangement, creating background music/beat, other instrumentation, mixing and mastering. The lyrics and vocal melody are already written.
