Website for a Trading Company

I’m looking for someone to build a basic website for our trading company. The website needs to include multiple features such as product listings, profile pages, and a simple shopping cart system. I will provide all the content for the website, but am looking for assistance with creating additional features like a customer contact form, or integrating a payment or membership system. The website needs to be optimized for both mobile and desktop usage with a responsive design. This project requires attention to detail and functionality, and must be completed in a timely fashion.
