College is a great time to start a business and become an entrepreneur. Contrary to the idea that having a business requires lots of funding, great skills and talent, or having a wide network of people who can support the business, business startups in college can be as simple as one's hobby-turned-into-a-business. And like other college startups, it just might grow big, too.

Here are some small business ideas that college students can turn into a business, according to Small Business Trends.

Personal Skills Businesses

Students who possess some expertise in a variety of things can offer to teach or guide different clients. Here are some ideas:

Personal Coaching - Students who are physically fit and active can help others get fit too. Offer your services to contacts who would want to get fit like you.
