I think I could come really close with 4 colors - White for ub and White (yea, I know), Red, Green, and Brown. With Black shirts and screen prep, I'd be at 12.70 each.
But for 16 @ 12.70 ($203.20) and 4 screens, sorry, but I would not even turn on the lights for that.
Let me know if they think they are a good enough band to sell 60 and we might work out a deal.
