Need background vocals arranged

Hi I’m in a 5 member group and I’m contacting you regarding background vocal arrangements. We have a song written and wanted some help on getting thick K-pop/Ariana grande like background vocals. I would like to know your pricing regarding a project like this. Please contact me at your earliest convenience.

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