Shopify Developer for Interactive Purchase Hub with Store Locator

We need an experienced Shopify developer to build a custom interactive Purchase Hub page that helps customers find the fastest way to get our product based on their location.

The page shows four purchase options (same-day delivery, store pickup, Amazon, and our website) that update dynamically when customers enter their zip code. All design mockups and copy are finalized - this is pure development work.

Requirements:
• Strong Shopify Liquid and JavaScript experience
• Amazon Buy with Prime SDK integration experience
• Store locator app integration (existing app already installed)
• Geolocation API implementation
• Database/metafields setup for zip code coverage areas
• Countdown timer functionality with business day logic
• Mobile responsive development
• Form integration with Zapier webhooks
• Experience with interactive zip-based availability pages

Deliverables:
• Main Purchase Hub page with zip entry and dynamic results
• Four social landing page variants (TikTok, Instagram, Facebook, YouTube)
• Admin-accessible zip code database using Shopify metafields
• Store suggestion modal form connected to Zapier
• Amazon BWP integration with delivery estimates
• Real-time countdown timer to 2pm EST cutoff
• Fully mobile responsive implementation
• Clean, commented code for future maintenance

This is hourly work with an estimated 40-80 hours total. We have complete mockups, detailed specs, and all copy ready to share immediately.

About the project: This is a well-defined build to replace our current product discovery flow with a location-aware purchase hub that will become our primary conversion page.
