The Streetwear Studio bespoke build a box

I need help developing my Shopify website, I am looking to build a page similar to this one (https://lbvintageboxes.com/?item=build_a_box). I will attach a screenshot to show the part of the page that needs to be built. Please have a look at it and see the functionality. The page allows uses to select different items to be put inside of a box eg a t shirt and build their own box. I would like to make the exact same however change some of the item names and have different prices for the items in which the customer can select. My business (http://www.thestreetwearstudio.co.uk) is very similar so it will be similar items eg tees, sweatshirts, hoodies etc.
