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:
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. I'm looking to hire a top pro who's worked on hit songs, and have the budget for that.
