You can have the very best hot dogs, but if you don't have a hungry crowd, you're screwed.
I got a call from a consulting client the other day.
He wanted to start a trade school for craftsmen... HVAC, drywall hanging, electricians, etc.
As far as easy money, I discussed with him how ... oh how... was he going to FIND this market. If you're selling a business management system to plumbers, you can find the plumbers mailing list and you can begin.
But how are you going to reach 19 to 25 year olds to teach them a trade?
Your cost of sale is going to be through the roof.
Then how much can you charge these young folks? Do they have the money to cover your selling costs PLUS everything else too?
Not to mention the competition you've got from youtube channels teaching everything from how to build a boat to how to pour concrete.
FIND A HUNGRY CROWD.... then sell your hot dogs. GUARANTEED SUCCESS.
