I found this shop in Cypress that can make the shirt but I don't like the shirt they sell. Going to bring my own shirts. She said its about $25 to embroidere each shirt.

I've had many-hundreds of Porsche, Ford, Canon, Zeiss, Fugi, PS Audio, etc. shirts and caps made...that I NEVER sell but often give away.
Send them an image and they'll digitize it for their embroidery machines for free.. When they have a sale, and that's more often than once a month, frequently they're 50 or 51% off regular price, and those are the only times I ever buy anything. There's never a charge for embroidering. During one of their 50-off sales, one can buy all- or 65%-cotton polo shirts for about $25 plus salestax and shipping.. Here are the colors I already have.. Oh yes...long-sleeve polos, too.
