mixing a track!

we'd be interested in mixing a single. there are about 40 tracks and it's in a french alternative rock style! we call it new rock! we don't know about the prices, but we'd like to know how much you could make it for us.

Additional info:
I'm interested in working with a very experienced mixer. The song has less than 10 tracks recorded that need mixing. I need it by 30 January, 2024. The tracks are cleaned, tuned, and and the song is ready to be mixed. I'm an indie artist. I'll need you to master it too if possible. Check out the song I attached.
