In addition to @apollolarosse's response, another method is to be one of his highest upvoters -- that's how I got to talk to him this weekend. I don't know what he charges for a private session -- that should have been one of my questions! :/ :D

I'll be posting a report on our conversation soon (dragging my feet for some reason; had neuro feedback yesterday and am usually irritable for days afterwards, although it is helping...).
