My best clients are from word of mouth. I see someone said to be certified as a QBs proadvisor.... I never had to do that and I am working over 40 hours per week. I did go to networking and chamber meetings. I got a couple clients from networking but none from the chamber. Linked In is beneficial, as connecting with others to let them know you are out there. So again, its all about networking from my experience. :-) good luck
