If I was in the admissions dept, I'd look favorably on an applicant who worked at a job.

I had a paper route, which was run as an independent business. I had a territory, I signed up people in it to subscribe, I delivered the papers, I collected the money, I paid for the newspapers the newspaper company dropped off. How much money I made was entirely up to how I operated. If I was sick or out of town, I had to find someone to cover for me.
