Someone to help boost our social media presence

I have a very specific requirement regarding an ongoing transnational project. The project already has some social media in place but we need someone to spend some time on promoting the project and reaching specific target audiences. This video should give you some idea of what we are trying to achieve http://www.youtube.com/watch?v=yjD4oPztcjM

We have a strategy which we will share once we have received initial proposals from you. Ideally you will have an understanding of how to lobby and influence government thinking as well how to build followers based on credible content
