Shopify Sales Boost Enhancements and redesign

I want to turn my current Shopify store into a stronger sales machine. The priority is measurable revenue growth, so every change you make should be conversion-focused and mobile-first.

Here’s what I need:
• A customer-review system that automatically requests, collects, and displays verified reviews and star ratings without slowing the site.
• Clearly presented upsell and cross-sell sections on product and cart pages, supported by a detailed mock-up before you code.
• A fully configured abandoned-cart recovery flow—email (and SMS if you recommend it), with split-testing to refine timing and copy.
• A short audit of my theme to flag any obstacles to these features and suggest quick-win layout tweaks for higher conversions.

Please share links to past Shopify work that proves you’ve lifted sales for other stores. I’m looking for someone who can supply a concise action plan, a visual preview of the changes, and a tested build ready to go live.
