Shopify Website with Klaviyo integration

Hi,

I need an experienced shopify developer to redesign an existing website with better design and features. The person should give us the theme options and the one that I like, we can go in for customization with that

Need only basic features-
- payment integration
- Klaviyo integration with subscribe pop up
- Design changes to be done until happy
- Review plugin to be added so that customers can get auto email when they purchase anything to give their review, preferably Stamped.io

The right person will have more work from me. You should start immediately.
