Need one song mixed and mastered

I wanted a professional mix and master for my first release. Its a hip hop song with a feature. Its got 23 stems and 13 vocal tracks. Please check it out and let me know what we should do and how much it is gonna cost. Thanks

Additional info:
I need the vocals tuned as well. I'm interested in working with a very experienced mixer. I need it by 31 January, 2022. I'll need you to master it too if possible. The song has somewhere between 30 and 50 tracks recorded that need mixing. Check out the song I attached.
