Youtube video editor for effects

I am looking for a Youtube-Video editor, who can edit my Youtube-Videos in the style of the random show of Tim Ferris and Kevin Rose: <[login to view URL]> So I would like to have inserted cool text slides within the videos, moving pictures of websites or google maps cards of places in between and also I need a cool intro in my companys CI. I am looking for a long term cooperation. So I do not really have an idea, how you can make an offer now. Maybe per video-minute or per effect or something... ?? ideas welcome.
