I certainly understand the pain and feel it as well. Unless someone steps up and gives all that you have mentioned we just have to keep, keeping on
Being far too broad with the niche is perhaps what I am guilty of as well being electronics and Michael in fact said something along those lines in one of his audios.
One issue is finding a niche like the web site you have kindly referred to. Guess it could be anything whatsoever as long as you become the expert in that niche, again like the site you have referred.
Seeing I have been made redundant need to decide where to go from here. Thanks for your comments and pray you do really well in your endeavors.
