Well that is annoying. You mean the link to the PDF, right? I just downloaded it and put it in my drive. Here it is. "So, you need an enamel pin supplier."
Thanks for clearing that up! I must've gotten them confused with another supplier. Maybe Vograce.
I've heard of Artscow (they also do several other kinds of merchandise), but they can get kind of pricey too... I think it's one of those places that people mostly use with coupons or go in together with other people for a group order.
Otherwise, you can try to find a Chinese manufacturer on Alibaba. It's like a... marketplace for manus, like Amazon or Etsy but for business services.
But if you want to make and sell dakis, make sure you're not undercharging yourself. I don't know what the market is like there, but here just the pillow case goes for $50-$70 a pop, easy. And you don't want to deal with providing the pillows, as that adds a lot to the shipping cost and takes up storage space.
Generally a good rule of thumb is to calculate your prices like so:
[Production cost] x 2 = [Wholesale cost] = What you would sell them for to a store so you both make profit.
[Wholesale cost] x 2 = [Retail cost] = What the customer is paying.
