Ask HN: Small volume printing of promotional items? (Calendars/etc...)

I'd like to get some custom printed promo items made up (Full color 12x12 wall Calendars specifically) to help fundraise for an online community I help manage.

I've looked at CafePress, Zazzle, Lulu.com, and their prices don't really leave any room for margin without gauging my community members (i.e. ~$15 in "hard costs" before any shipping fees or profit, means people have to spend $25-$30 per calendar shipped). I've also checked out local discount photography places (Costco/Walmart), and while their printing prices are actually slightly cheaper than the aforementioned websites ($10-$13 per calendar), they really aren't designed for this purpose, and I would surprised if there wasn't a better option out there.

I've investigated large printing companies, like 4over.com, and while they have substantially cheaper prices ($3/calendar), minimum order quantities are in the XXXX's, which is well beyond my needs.

Does anyone know of a service which can provide small volume (50-100 copies) printing of Calendars at discounted priceS? I.e. something like a Print100.com (HK drop-ship printer) but that can do 12x12 calendars? (Print100 only does the small desk style).

Thanks!
