I was wondering how much will it cost to mix and master in Dolby atmos for one song

I have a project I’m working on at the moment I was wondering what’s your price for Dolby atmos for one to five songs done

Additional info:
I'm looking to master at least 5 songs, possibly more. I need the mixer to do some editing, time aligning and vocal tuning before mixing. I'll need you to master it too if possible. I'm interested in working with a very experienced mixer. I don't have a hard deadline for this. Check out the song I attached.
