Website Design for B2C Marketplace

I am looking for a website designer to create an attractive environmental marketplace where customers can estimate their environmental footprint and purchase offsetting products. The marketplace should be built on Wordpress, allowing me to do minor adjustments myself in a later stage via my wordpress/Elementor account.. I need a custom design with some advanced calculation tools that stands out and displays all necessary information to visitors. I also require some specific tools for web shops, like account pages, payment integration, product reviews and others. This project includes only the construction of the website, All graphic design of logo's visuals, etc.. will be part of another project.
