If you have or can get your CDL, you can go to work the day you get there.
If you have a CDL and HazMat you can get hired on at almost any frac company right now (stay away from PumpCo for right now, talks of cutting crews right now b/c if they keep fracking as fast as they are they will run out of work in Sept and not pick back up until Jan '13. Cutting crews to try and slow down some fracs)
Working for frac is EASY! Hardest part is rigging up and rigging down (swinging a sledge hammer). They only drive tractors with pump trailers from yard to frac pad. Then you ride in shuttles until that well gets fracked, then you drive the truck to next location or back to yard. Low amount of driving. Average income starting is $80-100k/year, except Haliburton seeing how they offer the lowest pay...
