Build Custom Product Shopify Store

I’m launching a physical-goods store on Shopify and I need the entire site built from the ground up. The focus is on custom products, so shoppers must be able to personalise items easily while still enjoying a smooth, high-conversion experience.

Core features I must see live before hand-off:
• Advanced search filters that let customers narrow results by size, material, colour and any other attribute we define.
• A robust customer-review system (star ratings, photo uploads, “verified purchase” tags).
• Real-time live-chat support that ties into my preferred help-desk app (Shopify Inbox, Tidio or something comparable).

Beyond those essentials, I’ll rely on you for:
– Theme selection or a lightweight custom theme that’s fast, fully responsive and SEO-friendly.
– Seamless checkout with major payment gateways enabled and shipping rules configured for my carrier accounts.
– Basic on-page SEO setup: meta tags, clean URLs, alt text.
– A clear hand-over package: theme files, app list, and concise admin walkthrough so I can manage products and orders myself.

Please bring prior Shopify experience with custom product functionality (Product Options apps, line-item properties, etc.) and be comfortable integrating third-party review and chat tools. Let me know your estimated timeline from kickoff to launch and any milestone you’d propose for design approval, build, and final QA.
