Are you talking taking the truck to them and having them do all the work? if so it sounds about right (for exchanges). Are they going to change gears, or install and exchange? I doubt you'll find an exchange, and if they are talking about pulling your center section, removing and replaceing ring gears, then setting the preload and tooth contact, and re-install I say their estimate is on the low side. I know I couldn't do it in that time frame.
If you are going to pay someone to change the gear-set, (remove and install new gears) don't go with the best price, go with the shop with the best reputation! It is real easy to screw it up, and there are 100 ways to screw it up. I've seen the work of some shops that HAVE a decent rep and wasn't too impressed. I'm not that impressed with Weller either, their catalog is handy but I've had to "fix" some of their rebuilds.
The big question is: are gears available? Just because they show a number, doesn't mean it can be supplied.
Try W.M Cohen on the east coast (Penn) or Anderson Bro on the West coast (OR) and see what they have in new or used gearsets.
Anderson sold me some aftermarket gear-sets when I was re-ratioing my 2 speed axles. So far I have had no problems with them.
