25% of each shirt sold, if your confident your design is good and will sell all t-shirts. Example: If they sell each T-shirt for $20 and they sold 100 you'd make $500. They'd make $1500. I'm sure they're stuff is more than $20 because it's near impossible to find a T-shirt now for less than that. If you can't get 25% just try and get something in the $500 region.
if u want 200 always jump the price, so if they whine u can have it lowered it comfort them make them happy no one loose and in the end u will get the original price u wanted or who knows if maybe more... just tel them 350 or so.. if they whine or something u can work and lower a lil bit either way u will win just don't go with a price that u want than u will loose
YES tell them you want x percent of every sale they make even if its like 10% it keeps the money comin in ask for 25% at first if you guys agree on this make sure its written on paper
