OpenCart Ecommerce Platform

I'm looking to create an OpenCart e-commerce platform for my drop shipping-oriented e-commerce business. My preferred design style needs to be modern and clean, and I expect to sell thousands of products on the website. I'm looking for a developer custom the OpenCart platform to meet the needs of my business. I need to extend the platform to meet my business needs through customized features and content. I want the developer to have experience with the OpenCart platform in order to ensure the website is efficient and the features are optimized.
