@lilsimsie has a really nice one called Funky Photo Studio, I tried to get you a link, but the online gallery is being very wonky for me today. The lot is a 30x30 and has 3 photography locations inside this building. She didn't put a GTW photo studio, but you can easily swap out one of the photography spots out for a GTW one (I had to use the move objects cheat to place it). If you place this lot, you'll need to have the move objects cheat turned on while placing it. Otherwise, a few of the outside plants won't appear.
Here are some pictures of it.
