At 10 years old, John Costello took it upon himself to sell chicken eggs from his family's hobby farm at a Carver County farmer's market near Watertown.
No parents. No siblings. Just John.
"He didn't want to be the little helper," said his father, David Costello. "He wanted to have the whole interaction with customers to himself."
By his senior year of high school, Costello was running West Metro Solutions, a company that refurbishes discarded office cubicles and resells them to other businesses.
Now a junior at the University of St. Thomas, Costello has balanced being a full-time student and his company, which has generated more than $1 million in sales so far.
The lightbulb moment
Costello followed his egg business with reselling used clothes and electronics. While placing his goods online for sale, Costello came across an advertisement by a business looking to give away its used office cubicles.
Upon further research, Costello discovered billions of pounds of office furniture are dumped every year into landfills.
His solution: Help the environment, and make a buck or two, by recycling those items.
