I want to start up a webshop

I am looking to start up a new enterprise by creating a webshop. The webshop will be selling physical products and I am not looking for assistance with creating product descriptions and images. I need help in the areas concerning setting up and managing the webshop to ensure that everything runs smoothly, including product listings and inventory management. Also, I will need help with payment methods and integration, as well as any other tasks related to ensuring my webshop is successful. The right developer should have knowledge and understanding of how e-commerce works, along with experience in setting up and managing webshops.
