Need professional 5.1 surround mix for 10-minute short animation

I've recently finished a short animated film, runs about 10-minute, that needs final mastering and 5.1 surround mix. Deadline would be 1) Finish stereo within 15th of January, and 2) 5.1 surround withing the end of the month.

Additional info:
The song has less than 10 tracks recorded that need mixing. The tracks are cleaned, tuned, and and the song is ready to be mixed. I'll need you to master it too if possible. I'm hoping to find a good mixer that can work with my limited budget. I need it by 14 January, 2019. .
