I am a 60 year old with zero professional automotive repair experience and I could replace two rear axle shaft seals for $14 in parts and 3-4 hours labor in my driveway. FYI

Putting it another way since you unwisely seem to rely on GM service departments for uncomplicated non-warranty repairs.......
Two 19259473 GM seals that list for $36.80 each plus 4 hours labor at $150/hr....equals about $680.

Need to back it up, since are the seal leaking since they are just old/dried out/cracking,
Or are they leaking since the bearings are worn out, and this is what is causing the seals to leak (oblong wear to the seal lips), and the bearings need to be replaced as well.
To take it one step farther, would break out the torque wrench to see what the break-away torque value is on the diff clutch packs (should be 100ft lbs) and if the diff needs to come apart to change the bearings, and diff clutch parks are worn, would be a good time to have them replaced as well. Also, if you have a leak between the diff to trans case, good time to pull the diff housing to change out the O ring as well.
