A little help with ZenCart Store - Expert Needed

I have a fairly simple little project for someone who is very skilled at ZenCart: 1. Every avenue through the store where the user can add a certain product to the cart needs to be cut off and they need to land on the itunes page for the app I am advertising through the ZenCart. (the appropriate links are listed in the product descriptions, each one is different) 2. I seem to have messed up the home page a little bit when I was adding the iphone apps in.. (at least I think it was fine before the iphone apps anyways) Mostly it looks okay, but if you reload the home page area a few times, you will see that sometimes the product arrangement gets messed up and the page rearranges the order of them... Whatever we can do to sort that out. So that's the project! There will always be little additions to the store here and there, so I would like to find someone I can work with who will be around to assist for the long term. Thank you very much.
