Hey man, there is no "quick route" to become a Lineman. It takes years of training and more time applying what you've learned to be a lineman. I just hope you're not just looking for a fat check, cause if it's not in you (linework) you're just asking for trouble, maybe even an early funeral. This is not a trade to be taken lightly. If you REALLY want in the trade go to the local union hall and inquire there. If you are accepted you'll find out in a hurry if it's for you or not. Good luck and remember you can't rush it.
