It also depends on the quality and the skill. Some people charge while they'd better start following a course in Photoshop because they are still beginners. These usually work slow, often charge per hour and don't deliver best quality.

Otoh, to do it right, one needs to invest in a good quality monitor that's hardware-calibrated, in software etc.

Most people's monitors are not calibrated. Therefore they won't  see those carefully controlled settings. Same goes for print. If you hand them a CD or DVD, they probably choose some supermarket print service.

So I guess it's best not to exaggerate. If you deliver the prints on archival paper, printed on a 8+ color printer, then show what you can.

But otherwise I wouldn't invest too much time. If you shoot raw, you can play a bit more with recoverable highlights (the brides' dress...ahhh!!!), and if you shoot jpg perhaps some curves and saturation, eventually a luminance mask for a few  "hey, this looks promising" shots. But I wouldn't start bracketing or cloning. In case you deliver on CD of course.
