I haven't worked with this agency specifically, but it depends on a variety of factors - e.g. # of animations, actors/actresses, reshoots, reviews, etc. and how in-demand the agency is. It can usually run you low to mid six figures.
If I understand, Font Awesome paid >$100'000 for a video, in order to ask for $30'000 on kickstarter? Or do you think that this video was cheaper? (good will because of the open source nature of the project, or some other factor)
