Jeez, printing in the US is expensive.
I've just tallied up the print costs via the UK lab I use and it comes to £150 ($245) plus you can buy 250 3 inch buttons for $50 so call it $300 tops or less than $3 per person.
Based on my recent pricing I would be charging in the region of $50 per person but if it is guaranteed sales to all 115 I'd discount this further - probably down to around $30 - $35.
