I like the aesthetic of the page and understand they are "talking their book"... but I have to wonder if there is any merit to the claims they state on the web page: "Today, the last generation of technicians is retiring faster than the next is being trained to replace them. ETA International reports that there is a critical shortage of electronics technicians. Universities educate electrical engineers but do not usually train technicians for electronics service and repair." [1]

Is there a real demand for these skills out there? What does the pay structure look like?

I assume these types of jobs would require lots of travel if you are not in a big city... or there are few opportunities if you do not live in a place with lots of industry. I have so many questions... As I near retirement from my first career, I think about doing something to stay challenged into my 50's and 60's.
