Master a song

Putting out singles for now. Made this song with a friend about how people comes and goes all the time. Do not get attached too much.

Additional info:
The song has less than 10 tracks recorded that need mixing. I don't have a hard deadline for this. I'm interested in working with a very experienced mixer. The tracks are cleaned, tuned, and and the song is ready to be mixed. Check out the song I attached. I'll need you to master it too if possible.
