Orchestration for Grease

I have an odd assortment of musicians to perform in the pit band for a school production of Grease and I am looking for someone to orchestrate the music for these musicians. The production is taking place in March, so I would be looking for at least a few numbers to be orchestrated by the beginning of Januray 2014, and the whole job completed by the end of January to allow us time to rehearse. I have the complete show piano/vocal score which I can scan and send to you.
