211130 small CMS

I have a site that sells 3 different categories of products category A category B category C The site is very simple, the home page has 3 buttons for each of the categories. I need someone to setup a small content management system so that i can add products to each of these categories. I want to setup the site so that users can then pay for these goods via paypal. This project does not contain any design work. I simply need someone to create a small content management system. Previous works and examples are a bonus... and please bid very sensibly as it is a very small project for someone with the right skills
