In that case,
this link is about the best answer I can give you. If you make a minor adjustment for the fact that I'm a little off in the head, it sums up the process pretty well.
As far as money, we got $100 cash at the end of day one, breakfast at the lodge every day, lunch and dinner at the college every day, then $300 cash at the end of the week. If you're frugal, I imagine you could do okay with very little more than that. I tended to go out at night and blow more money, but that's just my style.
Once you go out with a trainer, then finish training and get your own truck, it's good to have some money in the bank until you get your legs under you. You'll suck at trip planning, you'll have things you need to buy for the truck, and you'll have a slow week right before your biggest bills are due. That's when people freak out and quit, then go to a new company, a new orientation, more training, and repeat the process. It's best to avoid that trap. Be ready for some ups and downs, as the pay escalates rapidly during the first year and you get better at the job.
By the end of year one, I honestly have to say it's the easiest job I've ever had. I don't have the family at home and the rest of the emotional baggage though. That is probably pretty rough.
