shopify shop 1 product

I am looking for a Shopify expert to help set up a shop to sell one physical product. This shop will consist of a single product page with associated images, descriptions, and payment processing (either through Shopify or an integrated payment gateway). I don't have an existing design to work with, so the freelancer will need to provide their own design from scratch. They'll also need to configure the payment gateway. This set up should be fairly straightforward as I only have one product to set up.
