Online store on Shopify

I need help in designing and building an online store in Shopify. Once you complete the layout , I will upload the content. It is an online store that will sell decorative prints. There are several categories of prints so each category will have its own tab. When customers click on the tab for a specific category, a gallery of images will open up so the customer can choose the print they will buy. When the image is clicked, the description of the print will show and the customer will choose the size and paper they want. Normally there is an option of three sizes, each will have a predetermined price , and finally the customer will choose between two types of paper. The paper choice does not affect the price. I will be selling retail and wholesale, so I need an option for a wholesale customer to login and see wholesale prices which are different than retail prices that the public will see. The content will be a the same for retail and wholesale except the price. I need you set up the store with a couple of products in each category, I can upload the rest once it is done and it works properly. This is a page similar to what I need: [login to view URL]
