Does Personal Digital Privacy Consulting sound like an insane thing? Is it already done for indivuduals?

I don’t think it sounds insane. It would certainly be a very niche market so you’d likely need to cast a wide net to find customers. Intel Techniques seems to offer these services and has a waitlist for customers. My question as a customer would be what your credentials are to help me? Ok, you do privacy as a hobby. Cool. I can go buy a 500-page book from Intel Techniques for $50 that will tell me how to do a lot of the leg work on my own to start living a more private life. What knowledge do you offer that I can’t get from the book for cheaper? I’m not trying to dissuade you because I believe competition is good, but it’s certainly going to be a hard market to break into and you’ll need a way to stand out.
