Modern Animated Instructional/Information Video

I am looking for someone that can edit our video to look like an entertaining (a little funny) where possible animated piece. The existing video can be found here...

Please can you send me examples of your work and how much it would cost. We are looking for a modern look and feel to the video

I like the styles of these videos..

It must have a voice recorded over the top and also feature subtitles at the top.
