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:
I don't have a hard deadline for this. 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'm interested in working with a very experienced mixer. I'll need you to master it too if possible. Check out the song I attached.
