If your a talented hand & a hard worker, my advice would be to roll up on some higher end jobs & offer to work for 2 days for free. Tell him if at the end of those 2 days, that he belives you'll make a good hand, he owes you for the 2 days, plus the rest of the week. If not, he's lost nothing by giving you a shot.
I landed 2 different jobs early in my career with that tactic. Got paid for my free days both times.
