Vocal tuning and editing for Youtube vocal cover

Hey would love to get a price for a single vocal track, edited and tuned for Youtube cover. It'll be on an ongoing basis - probably once or twice a fortnight so a continuous relationship is something I'm keen on. Will be great to hear some examples and prices please :)

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