Are you actually with or signing with Comcast? Definitely more length than I've ever had to put down, but usually that's done at no additional cost IME.
God knows they have an easy monopoly in the cable sector.
Look into temp agencies that specify in cdl work if you haven't.
They can pay pretty well, but honestly will still likely want more than what your schedule allows. Probably your best bet imo.
Did you see the one recently where the lady snake handler got bit and then started getting constricted upon?!
Did a pretty good job of keeping her cool.
