Website Designer (Remote)

I want to have a professional website made. It will be a website where customers and companies can start selling their products. Just like Ebay, but small. We want to start the website small at first with the option to expand the website later when more customers come. We want to be able to fill the pages ourselves with texts and photos. We have drawings of what the website will look like. We are really looking for a website designer who knows his trade well.

You must have experience in creating a professional website. I would like to see examples of this. We want to pay a fixed amount for the assignment.
