Invision board 2.0 + Google ads Modification

I need a modification designed for Invision board 2.0 and up (compatible with 2.1 as well). The modification should be as follows. I need to be able to manage in my admin panel which forum id's to allow this modification to work on (because some people have different forum id #'s for their classifieds section than i do). In that I want to be able to add google adsense code to be shown in the first post of the topic that has been started. Here is an example of it in action (but not for invision power board). [login to view URL] as you can see the script should insert the code for the ads first then allow the information the user has posted to show below it. This also needs to be writen as other invision modifications (found at [login to view URL]) SO there should be an install guide, what files to edit and where, and any files that should be added. Please see the uploaded file as a reference. This is one that is not related but shows what i'd like. I want to use this for many of my forums so it should be able to be installed by anyone (see file uploaded) You will not have access to my server so it must be in this format.
