I know rmoagency.com didn't work for what you need/want. Another option is contractorpower.com. Norm has a database of 1000's of contractor contacts. You can use his service to contact specific groups. He can narrow down an email blast for you of CA only contractors holding a specific classification. You could put together an email that he will send out for you. That way you can target license holders directly. Give them a call.
