Website Review/Critique

We are a Social Networking type of site, growing quickly in certain areas of the world. This is why we will need different points of view from around the globe. We are looking for approximately 10-15 different providers from around the world to review, critique, judge and give us an all around honest opinion of ways to make our website better. Ultimately we would like to hire around 5 of the groups with the best ideas and information to work with us continuously. We need basic page ideas, layout, font, ad placement, color, new additions. *****This is an ongoing project for the providers we choose******
