Yep, or Zoo Printing (no relation) has a nice range of size options and they'll do the hole punch too. 4over, you need to find a business card or postcard size that works as a hangtag and punch yourself.
A lot of this stuff, well, I hate to say it but it just ain't worth it to screen print unless there is a specific look desired that only screen can achieve and/or it's a massive run.
