I doubt it starts that way, probably more like a Google search for “wedding photographers near me”, a few names pop up, you go there, start signing paperwork and getting signed up, and then when you put down your two names, they look at you with disgust and tell you to get out of their shop, interrupting your thoughts about normal stuff like marriage licenses.

So then you take your shaken fiancé from the store, and look for other wedding photographers, and probably learn that there are far more Christian photographers than you thought, and not many that would preside over a fairly mundane marriage, save for the fact its just two guys instead of a guy and a gal.
