Billie Eilish-Style Backtrack Creation

I'm looking for a skilled music producer to create a backtrack for my song. I do not want to re-record my vocals; I will provide an existing recording that must be used.

Requirements:
- Dark and mysterious atmosphere
- Inspired by Billie Eilish and Vampire themes

Ideal Skills:
- Experience with synths, guitar riffs, and heavy bass
- Strong production skills in creating moody, atmospheric tracks

Please ensure the backtrack complements my vocals seamlessly.
