Need backend integration into template

I am interested in a 'Top 10' hosting website. I already have the design template..now I need backend integration so that I can have features similar to [login to view URL], BUT not that extensive. Basically, I am looking to integrate a backend admin area so that my site can be edited easily (change out hosts, banners, adsense, contact info, etc.). I do NOT need a rating system, forum integration, etc. Looking to get started ASAP. I don't know what this may cost, so I listed under very small. Thank you, Rob
