Hi CowCountry...,
Well before I even attempt to give you a link or a lesson on how to create or customize a template, I need to ask: Do you actually want to create your own template? and if so do you know HTML or someone that does that will create a template for you?
If you just wanted to use our free templates and have the sections like "Shipping" and "Payment", etc. show up then you have already done the work by creating a "Seller Details Profile". All you would have to do to use them is to select a template from a the "Lister Page" on any of your listings, then select a seller detail profile that you would like to use.
