seeking professional demo

This is for a musical I've written - all my music. Seeking someone to take my terribly sung/played demo and rerecord it to sound Very good. Like all musicals, the music should start out small (just a tinkling piano) and increase with more power and instruments until it's a big song. Only 2.5 to 3 minutes is fine. If you go over, that's fine. It's jazzy pop but becomes closer to rock. Any questions, let me know. I'd prefer someone who sings in English or at least has no accent when he (man sings this song) sings so the lyrics are clear. Will pay $100. Thanks.
