Edit short (2 min max) reference videos

We have lots of success stories, and reference materials from our customers. We need someone to produce industry specific short videos which we then can upload to our website, vimeo, youtube, facebook etc (need advice on best media too). The video will need to have voice over with British accent, subtitles and some music clips. We will provide the content, reference materials and color scheme can be taken from our website. This is an ongoing project and after we do one video we will need more.
