Not trying to be a mediator here, but chads right.
Someones idea of a 'quality' respray might be poor in someone elses eyes. What type of paint was used, would it react, what barrier material (like barcoat) might be needed, whether it would need just a rub down or full strip. Does it include engine bay, wheel arches or just above? Is it two tone, type of primer to hide any previous bright colours, list goes on.
I work in IT and its the equivalent of someone ringing up and saying 'my computers broke, how much to fix', could be a million things affecting price.
Not having a go, just trying to help you see if from the Painters side.
No such thing as a standard respray price.
