Evan Jensen, 18, rests atop his shower truck, which he helped build along with his family after noticing there was no place to get a decent shower in the oil boomtown of Williston, North Dakota.

With promises of six-figure salaries, workers -- including Jensen's brother -- have descended upon Williston, leaving a short supply of nearly everything, including housing and a decent shower. Many entrepreneurs, like Jensen, have seized the opportunity to fill the demand and try to make money themselves.

Jensen's shower trailer is open for business when most of Williston's oil workers are done with their shifts, between 4 p.m. and 11 p.m. Before Jensen came to town, many oil workers in Williston, North Dakota, had to wait hours or drive for miles to get a shower, usually at a run-down truck stop.

Jensen came up with the idea to convert his dad's old "dry van" trailer to fit five separate shower stalls, each with a private entrance.

The five showers run off an adjacent water tanker.

Jensen charges between $5 and $10 per shower and has an average of 25 customers a day. He's hoping his business will help him pay for his tuition at a music college in St. Paul, Minnesota, which he starts next month.
