I need someone to mix my vocals for my new single.

The song is a psychedelic, trap, travis scott influenced song, with a tad of the weeknd. The beat has already been mixed and was sent to me as an audio file, so the only thing I need is the mixing of the vocals. There is a lot of background vocals that are supposed to sound atmospheric, as well as melodic rap vocals that i would like to be in tune without sounding too robotic or filled with autotune: my preference would be that it sound very natural while still hitting the keys without sounding like autotune is present.
