Implement Shopify homepage from HTML/CSS mockup

I have a complete HTML/CSS mockup for a new Shopify store homepage that I need implemented. All content, colours, layout, imagery, and copy are finalised — no design decisions needed, just build it.
The site is on Shopify (Dawn-based theme). You can implement using either PageFly or custom Liquid sections — whichever you're most comfortable with. The homepage must be editable through the Shopify theme editor or PageFly after handover.
Sections to build (10 total):

Announcement bar
Hero with product image and two CTAs
Trust bar (4 icons)
Product cards grid (3 kits with pricing)
How It Works (3 steps)
Comparison table (old way vs SimpleStrip)
Customer reviews grid (6 reviews)
Video section with stats
Guarantee banner
Final CTA + footer

Requirements:

Fully responsive (mobile, tablet, desktop)
Links to existing Shopify product pages
Must match provided mockup closely
Clean, maintainable code

I will provide: Complete HTML/CSS file, all product image URLs, all copy
