Activity for Heather

I'm planning on taking a picture of our fur babies and have them each hold a sign 'our humans are getting married' and 'save the date October 7, 2017'. I want to print them like a postcard. What's a good fast place to get these ordered?

Where is a good place to buy coozies in bulk? I'm looking to make them myself but I am open to just having someone else do them if the price is right.
