(CNN) - A teenager's need for a shower sparked a money-making idea. After spending a few hours at a North Dakota oil field, Evan Jensen could smell the opportunity. And his idea is helping pave his way through college.
It's orientation day at Mcnally Smith College of Music in Saint Paul.
"I love composing."
While many in the freshman class are worried about how to pay for classes, Evan Jensen has a plan in place.
"I was excited, I knew there was a lot of things within our reach."
It started with a family visit to North Dakota's oil fields last Spring.
"Hours went on we got smellier and smellier, sweatier and sweatier. We were sleeping in our truck and pretty soon the idea came, holy cow, what'd I'd do for a shower out here."
With thousands of workers camping out daily, the wait to shower can be 3 hours long. Evan wanted to make a shower house. So, he earned money for the down payment by trapping muskrats.
"I live in South Dakota and there's tons of those and they bring 10 bucks each. I worked up about $15,000 dollars and since I had that in my bank, my parents were like 'go ahead.'"
The 53-foot trailer has 5 private shower stalls.
"They also have a little sink in them, some mirrors and a chair to change."
The average oil worker makes $90,000 dollars a year, so most don't think twice about spending ten bucks for a 30 minute shower.
"It sounds like we're robbing the people, I feel a little guilty about it, but it's a competitive price."
Evan now is trying to find the harmony between the successful business and pursing other dreams.
"I've always wanted to do music, this enterprising, all this stuff, this came in the last year or two."
Evan says it's tough to run the shower house because it's six hundred miles away from school.
So, he's selling it on Craigslist for 95-hundred dollars.
So far, no takers.
