Copyscape.com Clone w/out curtain features.

Hey i am in need of a [login to view URL] clone, but with some fewer features. First, it doesnt scan a website, instead a user can paste up to 1000 words into a text box then uses that for testing. Once it finishes testing, it needs to display a %of copied material. Also on results page, the original document would be on left, with highlighted text that was copied, and the highlighted text would corespond with a same colored source on the right side, that when clicked, shows site in frame w/ highlights on copied material. Also they colors should differ in severity. Payment will be made in escrow so please feel free to PM me with any questions you may have. Thanks and happy bidding.
