Software Development/Cloud Support

Our client runs education blog and they offer free intro software development, cloud computing and other technical courses. We need someone to answer any questions that they need help to answer or provide directions on an ongoing basis. You don't have to know everything as long you are willing to research and respond/help. These will be short answers. If they need extra help or detailed response or tutoring, our client will pay extra as needed. Give us estimate per question. Multiple openings. (This is an ongoing position where some weeks might have lot of work and some weeks will be slow). This is a free service and they don't really have big budget- Just FYI. Thank you in advance.
