You really need an open mind for this business, but if you can think outside the box, I really believe this idea is a winner.
This an idea I had for a membership a few months back after seeing a news report on high school drop outs looking for new career paths and training.
In this membership site you would tell people about what kind of jobs they can go for without needing a degree or even a high school certificate.
You'd be surprised at what jobs are out there and are willing to train employee's and pay rather large amounts of money to do so.
Basically you would be providing people with information on high paying jobs they can go for without needing any formal education at all. You could also have a job notice board in your site as well where employers post job ad's.
