Video Creation and Production

We're trying to look for someone who can create a creative/strategic/promotional video from a set of content. The video will be uploaded unto a YouTube channel. The video content will be for public consumption and will lead to creating a community of subscribers for brands so we're looking at a combination of a personal, creative, and screen casting video. We need to see a real person in the video at the same time we also would like to see professionalism and quality in the content. The video will be for a human resources related website. Once chosen, the service provider might become a full-time partner for video production. Previous samples of videos will be needed for qualifying final candidates.
