Jobs for Class 1 license?

Looking at doing Class 1 license MELT, then try to get on to operating a boom truck and move to mobile or tower crane operator. Fars I understand, most construction companies need Class 1's to truck counterweights and crane parts and stuff around to job sites so it could be a good entry point.

How's the job market for Class 1 jobs? I'm not interested in straight transport trucking so much as the entry into operating cranes eventually and everywhere tells me the Class 1 is basically mandatory to get into that line of work especially for mobile crane gig.
