How much to install ladder bars???

Looking to ditch my super stock springs in favor of ladder bars and coil overs. What's a ballpark figure for parts and labor, not doing anything but removig all the leaf spring stuff and putting in all the ladder bar stuff, car has already been mini tubbed so that's not going to be necessary. Going to take the car to one of our local reputable shops Friday to get an estimate and I want to have a ballpark figure in mind. Thanks.
