Physical Products Shopify Site Development

I am looking for someone to take my current site and transition to a new theme. I created this over the last coupe of weeks but do not have enough experience with websites to make it better user friendly and more aesthetically appealing. The attached version is from a free theme. Looking to pay someone hourly to help transition and build a better overall site.

Key requirements:
• Design site layout/navigation that is user-friendly
• Implement and test checkout functionality
• Set up secure payment options
• Promote SEO-friendly practices on the site

Ideal candidates should have:
• Extensive experience in Shopify store creation
• Familiarity with eCommerce best practices
• Strong understanding of UI/UX principles
• Ability to integrate potential third-party applications in the future

Please apply with past Shopify websites you've built preferably selling physical products.
