Acoustic Song Needs a Chorus

I am looking for a songwriter/guitarist to create an original new chorus for a finished song. I am satisfied with the verses, pre-chorus and bridge. The chorus right now is too slow - I am looking for something more upbeat. Please contact me if you are interested and I will provide further information. A file of the original is attached. Thanks!

Additional info:
I don't have a hard deadline for this. I'm an indie artist. I need the vocals tuned as well. 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 hoping to find a good mixer that can work with my limited budget.
