Place that does custom name or print on clothing?

So I am looking for a place that would simply put a custom name on a piece of cloth. Nothing fancy just some standard text. Kind of like names on the back of jerseys. Like white vinyl letters or what ever they are made of. Hopefully they might have a few font options. They do need to me white though.

This is a uniform that my dog needs to wear. He is a therapy dog. He does a lot of activities. The uniform is custom made I had to purchase. But I hated how they did the name. So I opted not to do it. ​

Yeah I know I can probably order the letters and iron them on myself. But I don't have an iron and wouldn't trust myself to get them straight. I have called sever sporting goods places and even places you can buy jerseys. They will only do it on clothing items they sell.

There is a kiosk in woodland mall but I have been there 4 times now not a single person around. I wait 15 20 minutes. Someone from one of the other kiosk asks. Tells me they went on break I even left came back an hour later. Still no one.

I have honestly been looking now for 3 months. Is there any place like this in GR?
