Design a professional easy to manage eBay template.

We require an attractive, professional eBay template created that is easy to manage and stands out from our competitors to give us an edge with our listings. Must be easy for us to manage to customise for different products and simple for us to insert different images etc. Happy for any freely available tools to be used to achieve this, but we must be able to reuse the template for many items easily and ideally without having to use any ongoing subscription services other than for image hosting. Can supply examples of the sort of thing we are looking for from other listings from our competitors.
