Let me expalin how a word of mouth job happens. A friend of yours you worked with sometime back who is working for a company calls you to let you know about a job.
You are busy but you have worked with a guy you know would be just right for this job. You call him and sure enough he is looking.
You tell him a friend you know called looking for an inspector and you will pass on his name to him.
You call the friend who called you and give him the contact and you worked with this guy and he will make him a hand.
They get together and if the $$ is right, one friend gets a job for another.
This all happens because people KNOW each other. I know people I would recommend in a heart beat for a job. But it is because I have worked with these people I would recommend them.
You build your network of contacts. This takes time. 3-5 years! I have been doing this for over 20 years and still have contacts I talk to at least once a year just to be sure phone numbers work.
