Where can I order customizable shot glasses?

I want to order customized shot glasses for my friends as a fun graduation present, but everywhere I look has either too high a minimum quantity (I'm getting about 20) or ridiculous shipping to Hawaii. Is there a place with cheap shipping and no minimum amount that does custom shot glasses? Just plain clear 1-1.5 oz glasses. (Not likely, but if anyone knows a place in Hawaii that would be great.)
