Need vocal for 1 song

I need female vocals to sing a melody, and songwriter (lyrics, top liner) and background vocals on a house music. I'm looking for a great singer to sing in the style of 'Chloë Howl'. We would send you the track we'd like you to sing. I would appreciate it if you could let me know the price and possible deadline. :)

Additional info:
The song has over 50 tracks recorded that need mixing.
