The only problem...Look at the quanities they want you to produce...but maybe they'll take pity on you or have some product they're doing for someone else that you might get for a song? :^))) Hope springs eternal.

You can go to China. There are few options here that appear to be minimum quantities that might be more to your liking (and some with min. 2,000 units). I don't know about your size situation. But again, the shipping will be a lot more than the actual unit cost (except I suspect that the ordering will be a "learning" experience :^))).
