Need Female Background Vocals of an Discohouse Song

We just need some background vocals for an discohouse song, only for the chorus (voice doubling of the male singer and 2nd voice). Its a easy job and it shouldn't be to expensive.

Additional info:
The song will be released commercially. I'm looking for a female singer. I am affiliated with a record label. . I need just the hook or chorus recorded. I'm hoping to find a good singer who can work with my limited budget. I don't need to use your name - you can be uncredited. The lyrics and melody are already written. I just need a singer.. I don't have a hard deadline for this.
