Article Rewriting Software and Word/PhraseThesaurus

I am seeking a programmer who has developed (or owns) an article rewriting / spinning software application. The bidder should be agreeable to provide a demonstration of their application. I am particularly interested in an application with a powerful Thesaurus that can handle multiple word synonyms. If you have had experience in developing these types of applications I look forward to hearing from you. NOTE: I am not interested in hearing from programmers who want to test their skills trying to develop a new application **
