Complete Shopify Store & Custom Multi‑Step Product Finder (Based on Prototype)

I am looking for an experienced Shopify developer who can:
1. Build my complete Shopify store (design, setup, sections, pages, navigation, metafields, settings).
and
2. Develop a fully custom, multi‑step Product Finder / Quiz based exactly on my prototype.
This is NOT a standard filter, NOT a popup, and NOT an app-based solution.
Only apply if you can custom‑code a quiz interface using Liquid, JavaScript, Shopify OS 2.0 and AJAX/Storefront API, and build full Shopify store structures.

Multi‑Step Product Finder (core feature)
UI & User Flow
Step-by-step questions
Icon buttons with active states
Progress indicator
Smooth transitions
Conditional logic
Desktop + mobile layout matching the prototype exactly
3 hero buttons on the homepage that preselect the first step

Technical Implementation
Must be developed as:
A custom Shopify OS 2.0 section or template
Built using Liquid + JavaScript
Powered by Shopify metafields for all product attributes
Real-time product filtering (no page reloads)
Using AJAX or Storefront API

Results Page
Only shows matching products
Custom layout (product cards + text + CTA)
Not a default Shopify collection template

Maintainability
Adding new products/attributes must require no coding
All attributes configurable via metafields
Clean and scalable code structure
