Put the word out. Just as the customers come word of mouth, so do the best employees. Just start mentioning to people what you are doing and what you are looking for. Network with other trades. They generally socialize with other "trade types" and that way the word can spread to possible candidates.

I would also look for local trade schools or junior colleges that offer NEC or trade classes. Put word to them or post on a public board (thinking cork type in a hallway, ot virtual). We have one local trade organiztion that has classes that young men will actually put themselves through. How's that for dedication? Not looking for a free ride. A little refeshing.
