Church Website Modifications - php/mysql & Smarty Templates

Please do not bid unless you have a feedback of more than 10 and a rating of more than 9. I have a church website that I need some items done. The main piece is to code out the new template (there are 4 or so that look very similar to each other.) Once they are coded out, I want the admin to be able to select which template the content goes in for a specific page. There are a few other small items to be done as well, but that is the main thing. There is already a full functioning admin section as it is. It just needs modifying.
