Creating a dynamic RSS Feed

I have a website for which I need a dynamic rss feed page created. I need an RSS button that I can add to individual pages that allow visitors to subscribe to a single RSS feed for the site (and ideally I'd like the small RSS icon to also show in the URL bar of my site). This RSS feed needs to be dynamic (not static). I would like the feed to automatically syndicate/update the latest 15 pages uploaded to the site. Please contact me for with any questions and for more details. I found a couple of websites (below) with pointers on how to do this but, honestly this type of coding goes beyond my skill set. [login to view URL] [login to view URL] Can you get the job done correctly and promptly? Thanks! P.S. All work would need to be backed up so that you will be able to restore the site should anything go wrong.
