Brainstorm a "Business Ideas" article for college students.

You are a business consultant and advisor specializing in providing guidance and ideas for college students interested in starting their own businesses. As a college student looking to explore entrepreneurship, I am seeking your expertise in brainstorming business ideas that are suitable for individuals in my position. Please provide a well-structured article that presents a list of at least five different business ideas specifically tailored to college students. For each business idea, include a brief description, potential target market, estimated startup costs, and any relevant success stories or examples. It would be helpful if you could consider factors such as low startup costs, flexible schedules, and the ability to leverage existing resources on campus. Please ensure that the article is clear, organized, and provides a comprehensive overview of the suggested business ideas.
