Website for a e-commerce website

My company is looking to get assistance with building an e-commerce website. We will be selling physical products, and want to use the Shopify platform as our main e-commerce platform. Additionally, we need this website to include payment gateways, so customers have an easy way to pay for products. This website should also be mobile-friendly, have a strong security system, and be SEO optimized. We are looking for a professional who is knowledgeable in website design and build, e-commerce platform integrations, and payment gateway implementations. We are looking for someone who is aware of the latest e-commerce trends, and can help us create a unique shopping experience that will attract customers. Ultimately, we want to find someone who can help us create an aesthetically pleasing website that is simple to use, while driving organic traffic and increasing conversions.
