Site Update

Hi, last year I got my first business client site, I did it all in flash.
Now I want it redesigned where the client can update the content by placing a text file and a pic into a folder themselves. Going back to change flash symbols to update is impractical now. (I know it didnt make sense in the first place as an novice I was given a chance and so I tried) any help? check out the site let me know the best appoarch to update the site Im open to all(advanced/simple) design and code options. Perfer the simplest scripting method im more of a design guy but I do have friends good at web languages and script.
