lot of companies over there and here who could use someone who specializes in Negotiations.

I'd imagine a few courses in the field and you'd be at the top of that field. You'd further understand all the legal things that might need to be addressed.

In addition perhaps you could become an adjunct professor at a University that simply teaches one of the topics you're really good at.

Good luck! If you want I can make a connection with my BIL and see if he has any connections for someone of your skills.

Best!
