Bold Colorful Shopify Store Design -- 2

I’m ready to launch my new line of physical products and I already own the domain—now I need a vibrant, on-brand Shopify storefront that instantly grabs attention. The aesthetic I have in mind is bold and colorful rather than minimalist, so the theme choice, typography, and imagery should all reflect that energy while still remaining easy to navigate on mobile and desktop.

Core functionality I must have:
• Product reviews displayed right on each item page so shoppers see social proof at a glance.
• A dedicated section or carousel for customer testimonials to reinforce credibility.
• A prominent newsletter sign-up that integrates with my current email platform to grow the list.
• Full Amazon FBA integration—orders placed on Shopify should flow automatically to FBA for fulfillment, and inventory levels need to stay in sync. (If you have a preferred app or custom Liquid solution in mind, let me know.)

Key expectations and deliverables:
1. Theme selection or custom theme tailored to the bold, colorful brief.
2. Page setup: home, catalog, product detail, about, FAQ, and contact.
3. Configuration of reviews, testimonials, and newsletter apps (or native blocks) so they match the site styling.
4. Seamless Amazon FBA connection tested end-to-end with a dummy order.
5. Basic SEO settings, speed optimization, and on-brand placeholder graphics where product shots aren’t ready yet.
6. A quick walkthrough (loom video or live share) showing me how to manage products, orders, and content going forward.

If you have previous Shopify builds with a similar vibrant look, please share. I’m looking to kick off right away and wrap up once everything is polished, functional, and ready to convert visitors into customers.
