Need iTrader v2.8 added to my vbulletin suite 4.2

My vbulletin site is live and running fine. (vbulletin suite is a forum plus articles and blog) I need to add the iTrader v2.8 addon, but I think it may be more complicated than I could handle myself. I have the iTrader v2.8 script and files. More info and even a support can be found here: (I have an active license - so I can get full access to support.) [login to view URL] I am just afraid that I will mess it up. So, I will give you the iTrader script and files. I will give you access to FTP and my site. All you have to do is get the iTrader to work correctly. \ Please read the project first and write the word "Understood". Also write your steps and suggestions to complete the project with a short description of what you understood.
