Ebay template generator software required!

Hi, We require a ebay template generator template software to be made. So this could be a WYSIWYG editor. Here is the PERFECT example of how we want the cPanel to look and function. Please take a look at this demo: [login to view URL] The ebay template generator will NEED to look and function like the above example provided with minor changes. Should function exactly to all statements on this website: [login to view URL] So over all, a client should be able to login to the editor, and create new listings, save listings, edit previous listings and then finally download the code and input this in ebay. Please have a look at the demo again as you can get an idea FULLY of what we require. The cPanel must also have a user guide. We will design generic front end so when client downloads the code, the design should appear with the fields created by clients in the editor. We need someone who is experienced in software development and who has knowledge in ebay. These two are complusory requirements. Those who have created such softwares or have 100% understanding of task will be contacted immediately. Look foward to your replies. Regards
