Your idea is fine, in theory, but unlikely to prove successful as people are protective of their territory.
I have previously assisted two young lads set up with on the job training, advice on chemicals and machinery, BUT, THEY WERE BUYING A MACHINE FROM ME!!!
In other words, there was a benefit to me in helping them, however, that was three years ago and within the Glasgow area with a catchment of only, around 2.5 million
They have a successful business and I have never yet come accross them business wise, but have sent afew jobs their way when unable to do them myself.
The other side, of the coin however, is the guy who worked for me for a year and constantly stated his wish to purchase my business when I decided to quit, which, due to severe problems with arthritis, sciatica etc, was my intention.
When I made the offer, he suddenly found he'd no money, but, decided to quit - mid November - and within a week was advertising in the same newspaper.
So, if you find c/c's in your area apprehensive, they may have had similar experiences to mine.
Anyway, good luck.
If you can work to a high standard and that's not necessarily what you see as a high standard, you will succeed. Unfortunately, if you work to a poor standard you might make more money, depends on your personal code of ethics
