Create A HTML generator in PHP or similar code.

We have a ebay listing template. [login to view URL] The problem with this template is it need to updated many times with different images and description. This takes alot of time and is alot of hassle. We need software in php or similar, that allows us to upload images so gallery is created. and add descriptive text. The script also will need to do retail pricing. Discount percentages and title. The script should save the details into a database, where it can be edited, deleted or simply browsed to. Deleting a generated listing should mean the images for it are wiped from the server. The Software should have a_) Login system b_) Handle multiple templates (template 1 and 2) c_) Be able to make changes to master template. Ie top links and other master template links. The software should also be able to exported to work with other style templates and stores on other hostings. When bidding. Please make a descriptive 5 or so line text with what you think the project is for. So we know you understand the project scope.
