20 Money-Making Skills You Can Learn in Less Than a Year

Private Security

Private security guards are often needed by retailers, public and private schools, bank branches and other companies. Duties might include screening visitors and monitoring grounds for suspicious activity.

You don’t need any specific education for these jobs, and many companies hire people with little to no experience and offer on-the-job training.

Experience in this role can be beneficial for careers in bodyguard work, private investigation and law enforcement, according to CareerBuilder.
