Create Multiple Website's from Master Template. - repost 2

I need a Website creation template system, that is great for SEO purposes. I like Wordpress as I have a number of Plugins for selling purposes. I am going to start Drop Ship Selling products, which is Basically promoting a product on a website (3-5 pages Basic), When an order is taken it needs to use a postcode lookup service (Postcode anywhere) to verify address and to then take Payment via Paypal. The system will then Send Email order to Wholesaler/Seller (Using the details I have set up there contact/email details using same lookup service postcode anywhere) the Wholesaler/Seller will then dispatch the order. I will need to have a simple order tracking system with export facilities of the data collected. The ability to create multiple web sites and emails quickly, is paramount and to take take payment back into the same Paypal Account, I have some good design skills and can make small text changes to my Existing website in .php but I am not a developer by a long shot. I have my own server details. **Please show me Template system examples that you have created websites from, please allow access for viewing only with relevant logon and password, so I can look at how the proposed system will look in principle **
