Mix & tune my demo track (1-2 vocals + beat, subtle Autotune)

I need a mixing engineer to mix and tune a demo track. The material: - 1-2 lead vocal takes only (no doubles, no backing vocals) + a beat/instrumental. - I'll send dry vocal stems (no effects) and the instrumental separately (WAV). What I need: - Clean vocal mix that sits well on the beat. - Subtle pitch tuning - natural, should NOT sound obviously auto-tuned. - Timing correction - tighten the vocals to the beat/rhythm. - Standard mix processing (EQ, compression, de-ess, reverb/delay as needed). It's a demo, so I'm after a clean, polished rough - not a full commercial master. Deadline: delivered within 1 week from when I send you the files. Budget: $50 fixed. In your proposal, please include: 1) 1-2 before/after vocal mix samples (similar style if possible), 2) whether you tune with Melodyne or Auto-Tune, 3) your turnaround time. I'll share the stems and a reference track with the selected engineer.
