Yes, its true. Whole bunch of SMEs more than willing to pay some cash as long as you get their problem rectify. Simple2 problem such as "My printer wont print", "I dont know why I cannot access my share folder this morning".
Go out there build your network and contact. As long as your attitude is good, humble, quick to solve their simple problem, you will survive or maybe build a small fortune. Once you solve their first problem and the boss grown rely on you, they will keep coming back to you for more.
