You ladies should consider giving 2 tickets to those photographers. I mean, if they desperately need experience, they'll take it for just a vacation,but being alone is not that much fun. So if you provide a ticket for their spouse, perhaps they can agree,if it's not a busy season. In Canada, I d'be really surprised if a photographer would agree to shoot a free wedding between the months of May-October.
Most are pretty booked at home. I suppose it's a bit different for the US,as southern parts don't have "wedding seasons", with all the worm temperatures even in the winter.
