The problem

Most 15-year-olds who want money get a job. I wanted to run one. The bet was simple: driveways get dirty, owners are busy, and nobody enjoys doing it themselves. If I could show up on time and do genuinely good work, the rest would follow.

What I built

A one-person service business, end to end. I handled the sales (knocking on doors and following up), the quoting, the scheduling, the actual soft-washing, and the after-service check-ins. No employees, no software; just a truck, a washer, and a standard I refused to drop below.

A DJ Pressure Washing invoice from April 2023, with a deck, fence, walkway, and driveway itemized by hand. The customer's name, address, and contact details are blacked out.
EXHIBIT E-02 · The first invoice, April 2023. One of 28 jobs; the customer's details are redacted.

The numbers

Twenty-eight paying jobs across two summers, just over ten thousand dollars, most of it from repeat customers and the referrals they sent. The books are on the homepage: every job is a receipt.

What it taught me

That sales is just showing up and being trustworthy, repeatedly. That word of mouth compounds faster than any ad. And that I liked building a thing that runs more than I liked being handed a paycheck, which is more or less why everything after this exists.
