That was a nightmare, but any good drywaller can shim easily enough.
Doesn't add much to cost.

In my area, tall walls are _shaved and shimmed_. One man on the
drywall crew uses an electric hand planer, long level and shaves the
wall stud edge a bit for plumb or staples on dense cardboard shims
(days ahead of the hanging crew). With 14 ft. ceilings it really takes
out all the waves or imperfections.
