The cost probably depends on the area of the country you're in. I personally haven't had that expense, but have read others who paid about $4,000.
I'd venture to say the vet's offices aren't being so much secretive...as they hesitate to quote a price on an animal they haven't examined and unknown variables.
Has your friend contacted her breeder?
Good luck to her...I know she must be worried sick.
