Make some changes to a wordpress theme & pages

This project relates to making some simple changes to the Wordpress theme "Renden" by "ThinkUpThemes" The wordpress site is already live/deployed, member access done etc. 1) Refer to the attachments "Featured Articles Front End" and "Featured Articles Back End" Currently the theme only allows for 4x of these content tiles. We need to be able to add as many as we want. They must show 3 rows wide (See "Adsense Landing" attachment), and then flow down the page as we add new tiles. (Up to 50 tiles) 2) Refer to attachment "Adsense Landing" Provision for us to add vertical Banners for Google Adsense must be made as shown in this image. (Script provided, you simply need to align etc) 3) When a user clicks on a featured content tile on the landing page, it will take them to a dedicated page on the site. The page will display a specific website (that I can dynamically change the url of) in an iframe. Above this will be a content bar, with a simple Home Button, and some text that I can dynamically edit also. To understand the layout and flow, please watch the video attachment and read the comments at the bottom of the video "walkthrough" The url that is displayed in the iframe, along with the text in the content bar will be different for each tile clicked! For example, If I click AUDI on the landing page, it will show a certain page (for example: [login to view URL]) , with certain content bar text (for example: welcome to the audi page, here are some instructions), and certain website in the iframe (for example: [login to view URL]) If I click BMW on the landing page it will show a different page (for example: [login to view URL]), with a different content bar text (for example: welcome to the bmw page, here are some rules), and different website in the iframe. (for example: [login to view URL]) THESE URLS AND TEXT ARE EXAMPLES ONLY, THE CONTENT MUST BE DYNAMIC SO I CAN ADD/CHANGE THEM LATER AS REQUIRED THE SITES DISPLAYED WITHIN THE IFRAMES WILL BE HOSTING SECURE PAYMENT AND CONTENT DOWNLOADS. (128bit ssl) THEY MUST FUNCTION AS IF THE USER IS DEALING DIRECTLY WITH THE WEBSITE
