webshop for cosmetics goods

I am looking for someone to build a custom-built webshop for my cosmetics goods. I need the webshop to be integrated with other systems, and it must have payment processing integrated. This webshop should look modern and be easy to use, and also display the products in the best light. I'm looking for someone who is experienced in developing web solutions and has a proven track record of delivering successful projects. Please provide examples of past projects as well as a timeline and cost estimate for this project.
