Niche website creation, marketing and maintance

I have a collection of several hundred pieces of mayan artifacts. Some are very rare. Many I know little about. This job would require you to build a website for use in English and Chinese. It would require you to research the background and history of some of the pieces in the collection. I have good photos and some description of the works. You will layout categories and pieces from the photos I will furnish. You will advertise these pieces on eBay, amazon and other sites. You will also find out the equivalent of such sites used in china. You will report all sales, interest and people wishing to know more about the art to me directly. You will need Skype or WhatsApp and have suitable computer and internet.
