Well, I have taken onboard what people have said, and in this day and age it is wise to be very cautious. Things have deteriorated one hell of a lot since I was a kid.

The only point that I would make is that if I wanted assistance with office, invoice printing, inventory control and the like, I would go to kids in the business studies class not those in a technical class. They would have no idea of the requirements, processes and so on.

Kids these days know about using computers, many know far more than older people. I would look for people who understood the requirement, as the technology is pretty basic and "out of the box"
