Create Visio diagrams for software project

Need to convert a set of hand-drawn software architecture diagrams into slick Visio diagrams. I would like these diagrams to stand out visually - not interested in plain, basic diagrams build using basic Visio elements. Will deliver scans of all the diagrams made on paper - they have to be made simple and consistent, and "nice to look at". There are about 10 diagrams to make I'm open to other diagraming tools as a delivery format, as long as I'll be able to edit them afterwards. ## Deliverables 1) Visio files (.VSD) 2) I need to be able to edit the diagrams afterwards and make changes. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Windows XP
