Store Developer - Shopify Website

My goal is to have a Shopify website that is focused on e-commerce sales for my business. I already have the website built and am looking for someone to host it on Shopify. The website will contain more than 10 pages in order to offer customers a comprehensive online shopping experience. Visually appealing images, attractive design, and a streamlined checkout process are essential to provide a high quality user experience. Furthermore, I'm looking for someone with extensive knowledge and skills in Shopify platform to help me create the store. I need to work with someone who can help ensure that the website performs flawlessly before launch and is maintained thereafter.
