website scooter-rental and online-shop for accessories and helmets

Hello, I need a new website for a scooter-rental with a modern and an responsive design (Wordpress). A theme could be the basis. It is very important that we can change and expand the content. Furthermore I need an Online-Shop for scooter-accessories and helmets The shop needs different payments (Pay-Pal, Credit-Card, Direct Bank Transfer..) and a good tool for SEO and Newsletters. An Amazon/eBay-Connection would be a nice option (this is not a condition). I want to use the shop-template also for other products.
