The first month will be a trial period that will be extended on a month to month basis depending on your performance. The right person will be kept permanently. If hired you will provide general website maintenance, update the site content as needed (picture sliders, content, pictures, text etc.) , troubleshoot marketplace issues and on occasion update the theme/plugins etc. We need someone who is reliable, can quickly complete requests and knows how to find solutions to problems without relying on theme/plugin developers to answer questions in their forum.
