Female Vocalist for Recording for music theater project

My name is Jonathan I'm writing a music theater project and need to hire a vocalist to do some recording. It's the apex of the show starting with a frantic dance bit loosely based on Beethoven's Razumovsky string quartet then into a vocal section. I need to reproduce a six piece vocal section in the studio. If you'd be interested I could send the track I have for you to get an idea. Cheers, enjoy your day! Jonathan
