Need licensed plumber to install shower in a business

Can anyone refer me to any licensed plumbers that can install a shower with a wall and door? It needs to be separate from the toilet or laundry room.

Plumber can be a hobbyist or non-hobbyist.

Relax upgrading their shower?

I surely hope so

Not licensed but I've laid some pipe.

I know a guy who specialises in this, he's the one that contractors hire to get luxurious kitchens and bathrooms done
