520800 Finish Tasks for Magento Store 2

Site: [login to view URL] Brief: Complete the following tasks so my Magento store is ready to go. 1. create a main category “Printing” with sub cats such as Business cards, postcards, brochures etc. that will lead to a new window or A- frame to a URL I will specify 2. Same as above only with another company for magnets and signs called “Stouse” ( I will give you the link to it as well) 3. Set up the site to accept credit cards thru PayPal but I don't want the customers to see that I'm using PayPal. Also enable manual credit card 4. I want the shopping cart to always be displayed and the cart needs to update without refreshing the whole page. 5. Go through the configuration so everything is ready to go
