Are there any T-Shirt printers in r/trees?

So my friend was talking to me today about how he was really into drawing. I've known he was into drawing for a while, and he is really good. He uses sharpee to make some pretty sweet stuff. He was saying how he wants to make T-shirts of his designs and sell them. He made this REALLY awesome drawing. So, this is probably the best one to put on a T-shirt, the other ones are cool, but this is one he liked, and other people liked. I thought I'd make it a T-shirt for him as a surprise, but I don't know how to do it. So are there any Ents here that can make cool T-shirts? And, I know beggars can't be choosers, but I would want to get him a quality shirt. Not just a picture ironed on there, but actually something that will stay there for a while.

So PM me if you know how to do this, and I will show you the picture. He worked hard on it, and I don't want someone stealing it, because I would feel awful. Thanks in advance for the help guys.
