Looking at the way he states there will be a 2 week delay I assume he'll wait for the peak and then go ahead and contact his printer (I assume he's got contacts to make it easier) and get the amount he needs printed, that way he keeps costs down (ordering in bulk). If he got to the point where he couldn't handle the orders himself I'm pretty sure he'd be in the revenue areas that allowed him to contract multiple printers to do the work, printing t-shirts in bulk is cheap.
