Change Joomla Theme Homepage

We have a new Joomla template installed on our website that uses a default landing page. We need the landing page to be the "Multipage Option" using "Full screen background" option. I simply do not have the time to do this and need someone that can complete the task immediately. I will provide login info. The instructions for completing this task can be found here: [login to view URL]!/documenter_cover This will be a very easy job for someone that knows Joomla! (IMPORTANT: DO NOT update our Joomla version - I will do this at a later time) I need this completed ASAP (within a couple of hours)
