Any time you use the word "scheme" to describe something, then it's doomed already not to work
And if you tack on "Get Rich" - well that's just a no brainer!
NOTHING in life is easy. It takes hard work and dedication.
Can you get rich after a lot of work? Sure, it's possible, however many people who launch their hosting companies will not make it more than a year, and a good percentage of the 10% remaining will never deem themselves as "rich".
There is profit to be made in any business (if done right, and enough time is allowed), but everyone is looking for the quick buck - it just doesn't work that easily.
