That part of it can be a good little hustle
People adjacent to my extended family in Ireland had a son who wanted to "be" a DJ and got done out of 5 grand for a course.
Can't hate on the graft
ouch. It's pretty easy now though. Not that I have a problem with digital djing. I'm no vinyl fetishist. A lot of vinyl djs have always been quite boring outside of jungle/dancehall/grime.
The software like virtual dj or tractor can guide you all through the process. 5 grand to learn something you can learn on your jacks in an afternoon? that's a lot.
