Need one song mixed and mastered

I’m working on some original Christmas music with a few friends. We need one song mixed/mastered. It’s an upbeat tune with piano, vox, and acoustic guitar as the main instruments. I’m wondering if a four-day turnaround is possible, or if that’s completely unrealistic. Thanks, and looking forward to hearing from you!

Additional info:
I'll need you to master it too if possible. I need it by 26 November, 2023. I'm interested in working with a very experienced mixer. The tracks are cleaned, tuned, and and the song is ready to be mixed. I'm an indie artist. The song has somewhere between 10 and 30 tracks recorded that need mixing.
