need a printing source!

I desperately need a good source for printing stationary like the one you see above by Sewing Stars. I would like to do stationary flats, greeting cards, and notecards for the shop but I need a good quality(and preferably less expensive) source! You can email me if you don't want to share your vendor(s) with the rest of the world but I would be VERY appreciative and might even send you something! Who says bribery is a bad thing? ;)
