Copywriter

I currently need a great editor who can make the words pop. Say it in fewer words. I'm looking for something on the back of my books, cd's for Upgrade to see actual infot a good writer a great writer look up Joel Roberts. Someone who can say it in fewer words and make you feel it! I also write workbooks and I need someone to edit, who will sign a confidentiality agreement and any work done will be paid in full here and I own all copywrite.
