Fix web page and set up Etsy store - Art Gallery

I have had the same static web page for 20 years - and sell mostly on Ebay. I need to have the links updated and key word optimization. I would also like help setting up an Etsy store. My web page is
WWW.LIVING-ARTISTS.COM and my Ebay is <https://www.ebay.com/str/livingartistsgallery>
