Mixing 1 song

I just have one song i was just curious of what u could do thanks. I just need it to sound better .

Additional info:
I don't have a hard deadline for this. The song has less than 10 tracks recorded that need mixing. I need the mixer to do some editing, time aligning and vocal tuning before mixing. Check out the song I attached. I don't need the song mastered. I'm hoping to find a good mixer that can work with my limited budget.
