Need help with my shopify store

I require assistance optimizing my Shopify store. There are persistent images I cannot remove, and I need help configuring the shipping page, creating an international shipping section, and adding detailed information for returns and policies. I am also open to future design enhancements to improve site aesthetics and user experience. Applicants should demonstrate Shopify experience, troubleshooting skills, and the ability to implement clear, customer-focused content and functional shipping solutions.
