Quick Simple CMS

We have a really simple Facebook shop which we use for our client's shops on Facebook. It's just a list of product hosted on our server with thumbnail images and links through to more info on the products on our customers websites. It's displayed on Facebook with an i-frame app. The simple html shops are already created but we now need a simple CMS creating so our customers can update their shops. --------------- We must be able to set up a username and password for each one of our shops so each of our customers can log in and administer their own individual shops using the below variables. - Upload head image - Marketing text display YES / NO - Category / learn more text colour - Marketing test header - Bullet point 1 text - Bullet point 2 text - Bullet point 3 text - Read More Link Categories View all link for each category - Add new Product For each product - Product category - Product Title - Link to product Thumbnail - Product Price - Link to product on website - Remove product - Hide / Show Product ----------
