firstly, searching should get you all the info you need, this has been asked many times,
best way to know is get a couple of quotes from different places, i work with a guy who used to spray cars, and im told that regardless of whether the paint is a pearl/candy or a single color it wont cost you much different, as the biggest killer will be the labour...
if the mark up on their prices isnt too much you should be expecting to pay from $1500-$1800 in parts/materials/paint.. the rest is labour
budget for 5k and hopefully youll see some change
good luck
