Change 4 small things in Shopify

Hey Freelancers, I need some one to change 4 small things on my coming shopify shop. 1. Under all my products do you have to add a box (See picture 1 under attached) 2. Under the slider do you have to add a box (See picture 2 under attached) 3. In the footer do you have to change my credit card info and add the ikon for the card I have in picture 3 in attached 4. You have to add more product to the front (under “Fremhævede”) 4 product in every row and I want 3 rows I have made all the graphic work so you only have to set the pictures in
