Good points, thanks. I believe I'll start with the "traditional" rationality stuff at first, since it's easier to give the impression of everything coming from a unified source that way. Also, I know it better than the other stuff.

I spoke to some friends who are familiar with this kind of thing, and one offered to give me feedback (both on the content, and for my presentation style) as well as possibly put me in contact with people who might be interested. I think I'll re-read What Intelligence Tests Miss as well as skim through a couple of other books on rationality that I haven't yet read, and then see what kinds of presentation ideas strike me as good.

They did mention that what I'm talking about is really more lecturing than consulting, but they say there's good money to be had that way too - presuming that I have the patience to build up a favorable reputation and references.
