Shopify Service Store Logistics Integration

I need a clean, conversion-ready Shopify store built from the ground up for a services-based business. All pages should be fully themed, populated with the photos and short promo videos I will supply, and optimised for mobile and desktop. The key technical requirement is that every order must flow automatically to my preferred logistics company. I already have their API documentation and credentials; you will just need to wire it up so service orders trigger the correct fulfilment workflow, tracking numbers return to Shopify, and status updates reach the customer without manual touchpoints. Once the site is live I want the admin area kept simple enough for me to update content, change prices and add new service packages myself. Deliverables • Custom-configured Shopify theme with my branding, images and videos in place • Secure payment gateway setup and tested • API integration with my chosen logistics partner, including end-to-end order test • Basic on-page SEO and speed optimisation • Short hand-off guide (or quick Loom walkthrough) showing how to add/edit services I value proven Shopify experience—please share a couple of stores where you handled similar integrations or service-based setups.
