Ebay Business listing HTML overhaul for business

We have 15 or so products we list on ebay. I want to clean up our current listing design and streamline it and make it more effective and efficent. I want it to look more modern and trendy and something our customers can enjoy and trust. At the moment its messy and hard to manage and insert new products easily. When we insert a new listing, we need to edit only the images and description, everything else stays the same, but sometimes this can be difficult to do. So we will require 1 HTML listing that we can insert that is upto a good standard. Please PM for more details.
