Digital Download Script/Plugin that pulls from directory

I need a Digital Download directory created similar to [login to view URL] I need to be able to put files in a directory on my server and the following happen: 1) Script/Plugin Pulls file-names 2) Creates page for that download 3) Seo features - Puts file-name in URL and in Title There are wordpress and joomla plugins that do this to an extent, but they do not create a page for the file. This project can be accomplished by modifying an existing wordpress (preferred) or joomla plugin of your choice. I prefer wordpress because I am most familiar with it and it would be easy for me to manage. If it is too complicated to do for wordpress or joomla, this script [login to view URL] can be modified to have the SEO features. PM me your suggestions/thoughts on how we could accomplish this when you bid.
