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