Business classes
Learn everything from how to write a business plan to how to finance your venture through the Small Business Administration's website ( Online courses are free and self-paced; they take about 30 minutes each to complete. Free in-person classes are also offered at SBA district offices and resource partners around the country.

Why's it free? The SBA was created in conjunction with the government to help U.S. citizens learn how to become successful entrepreneurs. Support comes through financing of SBA loans.
