This paragraph sums it up pretty damn nicely.
If you want REAL training for these skills, seek out someone who has "been there, done that". You are most likely to find them teaching a night class maybe on-line, at a community college or as an adjunct professor.
Of course, there is no guarantee you will find them there because many of these positions are filled by wannabe tenured professors, most of whom are too divorced from the real world to do the job. Start by looking for professors at least 40 or older with solid resumes in the business world.
My problem with business school and the entreprenuerial courses is they teach you the theory but not the actual application.
So yes a person can do the business plan and present it, but not understand how to go out and get the licenses and registrations required to actually start the business compliantly - once they do... their biz case is different due to all the regulatory burden and it makes less sense then originally proposed.
