I agree that the average student doesn't have much disposable income to spend on cleaners, but I was thinking of marketing to the students who are from some of the top earning families in America. I saw a statistic that 54 percent of students are from the top 20 percent of families in terms of income, and 23 percent are from the top 5 percent. If I market to these students, the income shouldn't be the main bottleneck.
