Groundman opportunities?

Just recently went to school to hopefully get into the line industry, I’ve been working as an electrician for the past 6years which I thought would be a huge help in securing a starting position at a utility or contacting company but seems to be impossible at this point. Any advice on getting started and where to be looking for job opportunities? I’ve signed both books in California for groundman jobs and was placed on book 3 but haven’t had any luck there either.
