Most true artist detailers charge by the hour, so the price you paid isn't something you should regret, unfortunately some detailers aren't worth that type money. When you can demand a dime for a detail, you better blow your clients away. A grand as far as I am concerned is translated into perfect defect free paint (which of course isn't always possible without touchup and sanding many cases) as well as a very thorough cleansing and dressing of interior surfaces. Every stitch of surface needs to be brought to it's highest potential, and completely shrink proof, and your knowledge (client pending) needs to sky rocket.

Of course a job like that could mean different things to different detailers but I would steer clear of anyone suggesting they will sand your car down for 400 dollars, like I said, you gotta go through thousands of detailers to find one sometimes.
