I need a website developer.

We are looking to create a similar UI/UX similar to that of the famous pupsocks. See the following links. Our product page right now vs theirs, https://www.pawsitivelyyoga.com/products/custom-yoga-mats and https://gopupsocks.com/product/custom-socks/ , respectively. We would like to have our UI/UX in such a way that we can have the customer do all the front-end design on the product page prior to sending off the instructions to our design team. We would like to have the customer go to the product page, select the animal image swatch of their choosing, have a dropdown box filled with examples of each of the available designs for the chosen image swatch, and when one is selected, the design be visible on the mockup to the left. We would then like to have a size indicator, and then prompt the customer to upload one to four images of their choosing (either of their pets or themselves). After that, we would love to have additional comments to the designer box for any additional comments necessary for our designers to provide the perfect product.
