Build a website for online streaming and social networking

I'm starting my own online streaming service aimed at creatives and independent filmmakers where they can upload and share their content with approval from our end. The website needs to integrate the streaming and social networking features in an intuitive and streamlined way. It needs to be safe and secure and to be able to handle a large amount of traffic at once. That's why I want to use AWS, I have done basic training for some aspects of it but I really need website developers and AWS developers to help create the architecture and systems in place. (Think of YouTube + Netflix)
