Marketing assistant

Looking for someone to help attend workshops for a prize our company won, and subsequently prepare investor materials (powerpoint presentations) and other content that the prize organizers require. Other assistance might be needed to help promote the company. Ideally the person will be located in Australia because that is the current need, or a similar timezone. Workhours need to be flexible because most of the rest of the team is based in Europe, so late afternoon / evening hours are more important than morning hours.
