Need 5.1 mixing(Dolby Preferebly) for my Mock Reel Project

Hi, I've directed & produced a 58minute feature mock reel film. Looking for a quality 5.1 surround mix. Want to bring out the best sound possible for my budget. It's a Psychological Thriller Drama. The deadline is 7-10 days from 28th August, 2018.

Additional info:
I'm looking to hire a top pro who's worked on hit songs, and have the budget for that. The song has somewhere between 10 and 30 tracks recorded that need mixing. The tracks are cleaned, tuned, and and the song is ready to be mixed. I don't need the song mastered.
