Build Drag & Drop Designer page

We are looking to have someone convert a page design into a function web page. The page is part of a UI for a system we are building. The page consists of a drag & drop network design area with multiple tabs of components available to create a network. Just looking for UI to completed at this stage so no real overall functionality required. It would be good to have this page ready to post data back to a database so if possible to include this in the development (basic co-odinations on the designer plus maybe the interconnection between devices). If you think you can help out, then please apply stating your bid and please show examples of any drag and drop style website you have designed before. Further details can be given on request and the design will be made available for the winning bidder.
