Turning a page please help

Hello everyone i am trying to make a book that the pages flip. The video is just for an in-office project and i need to get a year book to open and flip throught the pages one by on (looking at each closely). I have seen

http://blenderartists.org/forum/showthread.php?t=19577

and this is where I got my turning page from. The only problem is the page needs to have a front and a back. right now there is only one page and the front is the same as the back. I cant figure out how to give the page a backing. extruding would make me have to rekey each of the other side. (if this makes any sense). Is there a quicker easier way to go about doing this? I have attached the blend file also. Poject due on monday so if anyone can help please.

Thank you
