Need a vocal for one song

Looking for a vocal (with lyrics, songwriting and top lines including BV and harmonies etc) for a new demo. Link to the demo :

Additional info:
I don't have a hard deadline for this. I need all the vocals recorded (lead vocals, harmonies, stacks, ad libs). I'm interested in working with a very experienced mixer. . I'm going to hire a different mastering engineer. I need the mixer to do some editing, time aligning and vocal tuning before mixing.
