We need an experienced Shopify developer to add a high‑converting “Contact Us” widget to our product page. Requirements: Add a “Contact us” widget on the product page, positioned below the product description. Use our existing Shopify theme (Dawn or similar) with clean Liquid code and no unnecessary bloat. Mobile‑optimized layout and responsive styling. Simple, professional form fields (name, email, message; you can suggest additional fields if helpful). Form submissions should send an email notification to us. The widget should visually match the store branding and not slow down page load. Please share: 1–2 Shopify stores where you built or customized product page widgets or forms. Your approach to implementing this with Liquid and keeping performance fast.
