Mix/master deal

I've finished my song and I did the vocal tuning/some mixing, but I'm not completely satisfied with it. I'd like to do the first client package (mix master and vocal tuning). Also, do you use melodyne and auto tune? I can send my version so you know the direction I'd like to go in and then we can go from there. I'd be super pumped to work with you so please let me know! Thanks
