i tell ya, i go in the local mall here in NC and there is a hat store called Lids and they can custom make a hat with what ever you want it to say on it,first you pick out the style hat you want then you take it up front and they ask what you want on it, tell them what you want then they will start the machine up and it stiches it up right there on the spot, and the ones i have had done are really nice and they look good.
the hat i bought was like 20 bucks, and i think after the custom work it was like 30 bucks for the hat, which is not that bad considering you get what ever you want on the hat and a hat that fits you right. some may be less and some may be higher depending on where you get it done.
here is the site that tells you about the store.
