Additional info:
I work for a business with music production needs. 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. I'll need you to master it too if possible. I'm hoping to find a good mixer that can work with my limited budget.
