I agree with above, perhaps ring and speak to some agencies and see what he might need to do and focus on one particular area.

My DH has worked for several years now in the industry but is a trained Diesel Mechanic. There are many jobs available it comes down to what you are willing to do and what you know. My brother really struggled to get in (he wanted to drive graders) but he didn't have the experience, he had to take jobs doing other things for some time before he got the job he wanted and this required lots of travel around.

We to have moved a few times in 5yrs for the job, or there is fly in/out roster systems.

Where are you located? We know plenty of people in the industry in all different states.
