I currently have a news feed program on iTunes App Store for the iPhone. I want to make some changes and add the "IN App Purchase" to the app and create a larger bank of options for the customer to purchase additional feeds.

So I would like to utilize the current code, but just add the "In App Purchase" and everything that goes along with it (new menu I assume, how it is structured, etc.

I am new to IN App Purchase and never used before, looking for someone who knows it well that can help and complete the project.
