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 need it by 26 November, 2023. The song has somewhere between 10 and 30 tracks recorded that need mixing. I'm an indie artist. 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.
