Article Rewriter Script

I am looking for someone to help me develop a web-based article rewriting script. The script will allow users to copy and paste an article into a text area. User can select portions of text from the article to "spin". Spinning involves creating variations of text using a special spinning syntax. ie. { text1 | text 2}. When the user is done editing, there should be some sort of rewrite button which will generate a unique version of the article based on the specified spinning syntax. ## Deliverables I mentioned that I would like this script to model Power Article Rewriter. However, I do have one extra feature I would like to have. I want the user to be able to be able to select from a list of supported Article Rewriting sites and the script will be able to handle the spinning syntax of the selected site. The first two sites I would like to support are [login to view URL] and uniquearticlewizard.com. The code also be designed in a modular way so that I can add support for other sites as necessary. The script should be able to handle arbitrarily long articles with no degradation in performance.
