Hugh Reilly, PGA will give you a complete swing analysis from address to finish.  The student is videoed from two angles, face on, and down the line.  An assessment is then made in the following areas:

Address Check points: Grip, Alignment, Weight Distribution, Posture, Spine Tilt
Backswing Checkpoints: Plane, Forearm rotation, Extension, Knee Symmetry, Spine Stability, Hip Set
Downswing Checkpoints: Swing Path, Hip Rotation, Spine Angle, Lag, Impact
Finish Checkpoints: Head position, Spine Tilt, Rotation, Knees, Left Leg, Stability

The student is then given a series of drills on how to improve these positions athletically.  Follow up lessons can then be scheduled to check on the students progress.
