Create 5 Iphone Apps from 1 Exisiting Iphone App

I have an iphone app launched in Itunes. It has many different functions. I would like to break out some of these functions into their own apps. Basically all the code is there in the app it just needs dividing up with some minor adjustments and additions to each app. This project will also involve making minor cosmetic changes to the original app and one small functional change. The coder is responsible for helping get set up so I can test the apps out on my computer and phone. Full payment will be made once the apps are all up and running, have been accepted by Itunes and I have had a few days to test them out.
