Make sure you can change their odds. Check a a few off-shores websites. None of them offer those kinda of payouts. The $1 min puts you in a nickle and dime business. What is the max bet? 1 $100 winner wipes out most all of the $1 tickets you can sell.
I have $5 min $100 max and I still fear the $100 cards.
As for putting the rules and payout on the front, Why? you can print them twice, side by side on the back, then print 2 cards side by side on the front, cut them in two Viola 2cards. I have all that shit printed professionally and the tear off portion perforated. Then I just stick the preprinted (legal size sheets) in my printer and put in the week to week stuff on the front. I have a paper shear where I can cut 250 heavy bond sheets at a time. Yields 500 cards. the heavy bond makes them feel like cards not paper.
