Cover of a choir (Short)

I need a choir cover from an old song. Should be as close as possible from the original. The only section that need cover is the one in the preview. No rush deadline, but would be awesome to have it as soon as possible.

Additional info:
The tracks are cleaned, tuned, and and the song is ready to be mixed. Check out the song I attached. The song has less than 10 tracks recorded that need mixing. I don't need the song mastered. I'm interested in working with a very experienced mixer. I don't have a hard deadline for this. I'm an indie artist.
