Shopify Product Page Customization

I'm looking for a Shopify developer to make a few customizations to an existing product page. Tasks include adjusting the product page layout, adding trust badges below the Add to Cart button, creating collapsible sections for Product Details, Shipping, and FAQs, fixing spacing and alignment issues on mobile devices, and ensuring everything works properly without affecting the rest of the store. The work should be clean, responsive, and completed within 1–2 days. If the quality is good, I'll have more Shopify customization tasks in the future.
