CSS master needed for width issue

I am trying to get a website to fit in a wrapper of my Joomla site, but it is too wide. I need the width of the website made to fit without messing up the rest of the site. I am guessing there is a quick css way, but I don't know it. This should be easy for someone with real skills. My budget is $30 and I need this done as soon as possible and will pay immediately upon completion. You can see what I am talking about at this page. [login to view URL];view=wrapper&Itemid=93
