Silk screeners
If you're doing polos you might want to get it embroidered instead of screened. It just comes off as a more professional look. However, if you're going tshirt, then you'll most likely find somewhere here that can help you out (and a lot of the silk screeners do embroidery too). I remember taking part in a conversation on here just like this about 2 years ago I'd say..not sure if the searches go back that far or not.
