I've been talking about this with a friend and he asked me: How do you get your first customers for a cunsulting business? What do you think are the best ways?
It is about whether one has a talent for this job. One has first to try unpaid activities, to your family and close circle of friends. If it works, try to enlarge your ground, until gets to paid activities.
If no talent for that, better go for engineering or management activities.
all the best
