Website Designer to revamp my current website - Shopify Expert

I need someone who can edit my current website - Im about to launch a new product so need to add these to my shop but also offer bundles that stand out and convert. I would also like to change one of the pages/tabs to now include a just launched section or whats new. Ideally would be good to find someone who can help with regular service of my website when needed. I need someone who can demonstrate strong graphic design skills and the ability to add good functionality to my website to help convert sales. This project requires a fast turnaround ideally 2-3 days. Thanks
