I know a couple of professional photographers and neither of them will do weddings. It seems many of the clients are as bad as the photographers.
In the same breath, those photographers will complain about all the "amateurs" devaluing their services.
Me: "I'm getting married on [date] and I'm looking for a photographer."
Them, in the voice of Nick Burns: "We're already filling up for next year. Good luck finding a photographer this year."
Me: "I just got engaged. You never have anything open up?"
Them: "No" and hang up the phone.
The faster guys like that struggle to make a living, the better.
