Shopify Setup for Locker Pages

I need someone to help setup Shopify for a limited test of locker pages. The hypothesis is community can generate commerce. Think influencer promoting a brand can send their community directly to the brand to purchase - not micro influencers a major brand's influencers. We are wanting to quickly spin up a shoppable page/pages that the prospect doesn't leave Instagram but purchases from the brand, not the influencer. The brand doesn't have a Shopify site, this is a test with "locker" pages only. Need to set up the account with a brand appropriate look and feel of the shoppable page/pages, ensure commerce can be transacted, tracking is in place (clicked link, landed on "locker", added to card, purchased, etc.). Orders will be extracted manually for the test - no 3pl integration needed.
