It seems that, even through examining the site you were linked to, most of the professional education oriented companies are geared towards technical skill-sets. There are webinar platforms for a bunch of the other things but those are, for the most part, one-offs. It's rare to find an effective staged learning system with excellent content. I haven't seen it much outside of academic platforms.
