Brainstorm a new business idea that could help college students improve their career planning.

You are a career advisor or an entrepreneur with expertise in career planning for college students. Your role is to brainstorm a new business idea that focuses on improving career planning for college students. College students often face challenges in their career planning journey, such as lack of guidance, limited resources, and uncertainty about future career paths. They need assistance in exploring career options, developing skills, and making informed decisions. Please propose innovative solutions and services that can assist college students in these areas. It would be helpful if you could consider their specific needs and challenges, and emphasize the importance of networking, internships, and mentorship programs in career development. Please provide a well-organized list or table, presenting at least three different business ideas, along with a brief description of their features and benefits.
