SEO Friendly URL Plugin Creation

This project requires someone with advanced PHP programming skills as well as .htaccess and rewrite skills. I have an existing program that pulls rss feeds for products, similar to amazon feeds posted on peoples pages. The urls are not SEO friendly. I'm capable of doing the .htaccess rewrite, however I want this ability to modular, i.e., I want to make it a plugin. I will need other plugins for the same application created, so this would be continued work for the right person. The budget is $50. This should take no more than 10 days. Whoever is selected will be utilized regularly for updating the plugin as the application is updated and modified. This means continued work. If you don't know about rss feeds, dynamic sites, php, and mod rewrite, don't bid. No automated bids will be acknowledged. If you have done work on oscommerce, zencart, or other applicable php development, this will be looked at favorably. If you have done plugins for php nuke, wordpress, or other platforms, this will assist you with this project. Thank you. P.S. Please do not call me "Sir", I am not a "Sir".
