Don't forget, every computer shop has software tools like these, yet they all succumb to the current economy and the big names.
I think the market is oversaturated and a lot more people are doing "scary command line stuff" nowadays, because Google actually has enough simple resources on it these days.
Only way you'll make it in IT in general is by having an expertise in something, and not to be a dick, but a software tool doesn't make anyone an expert data recovery engineer.
As I said, I don't wanne be a dick, but I also don't want to see people put money into stuff that will miserably fail (like setting up shop).
