Create product page on existing wordpress site -- 2

Hi there, Need a product page setup on my existing website: [login to view URL] I want a similar look to the following setup: [login to view URL] Landing page would have three different categories: Love letters DIY Ceremony Then users can click through to the individual categories and products: With the products listed horizontal and opening up to a larger pop-up. Four items across please. I'd like it to be so we can add individual products easily ourselves as we get new items. I will send through imagery etc. once the initial template is setup. Please let me know if you need anything.
