For this small size of ecommerce solution, you dont need to make site. Better you can avail shops for rental in saas concept. you can have your own shop on ZScart - saas ecommerce.

 

coustam jquery carts will be fine no need to zen cart ecomerce etc

 

I too prefer ZS Cart which is good for the digital downloads & it is the use ecommerce software system.
