Don't charge by the hour or pay by the hour. Charge/pay by the job. I don't do weddings-did one and learned how much I hate it. If you charge by the hour you will feel rushed and your shots will look it. If you pay by the hour you will feel rushed and the shots will look it. Better for them to find a photographer sit down then sit down and talk about exactly what they want and see if they photog can do that.
My brother in law and his bride were shown 200 images on the "preview website". Out of which 3 were impressive shots and the rest were shots a monkey could have taken. This whole more is better is crap.
