Hi, Jackie, welcome aboard.
Prices vary indeed. The least you'll find by a competent shop is going to be many hundreds of dollars. It's a bit of labor to get in there, then the labor to get it out, then the labor to swap the motor to the new part, then all of the reinstallation.
You should also know that virtually no good, competent, reliable shop will allow you to bring in the part. The profit they make on selling you the part is part of the warranty they provide. If they do let you bring it in, they may pad the charge, and, worst of all, you won't have any kind of warranty if it breaks. (Side note: speaking from my own experience and that of others on the forums I would avoid autopartswarehouse, they've gotten very flaky over the years. There are lots of good online vendors, including those dealers who sell online, such as mboemparts.com (Mercedes of Naperville).
The other thing to think about is that the largest expense of this job is the labor.
Thus, the very last thing you want to do is skimp on the quality of the part that is being installed. It would truly suck to pay $480 (or some other stunning sum!) for the repair and then have the cheap part you supply fail in only a couple of months. Sure, you may have a warranty on the part, but you're going to pay labor to remove it, and then you can box it up and pay for shipping (insured, of course) to send it back to the seller so that they can verify the warranty covers the failure. In the meanwhile, your window won't be working, maybe the shop can jam something in the door to hold the window up, but it won't be a functional window for perhaps a week or two. Then, when you finally get the replacement part, you get to pay labor to have the replacement reinstalled. By that time you could have bought a whole new door, not to mention all of the frustration.
The final thought here: how do you know you need a window regulator? There are all kinds of things that can go wrong with the power windows, and if you carry in a regulator and say "change it" that's all they're going to do. Then there's the possibility that you come back and pay them...and you still don't have a working window.
So the best advice I can offer is this: find a good indie shop (I would avoid the dealer for this) and have them diagnose and repair it. Then they are responsible to make sure it works and you leave with a warranty on the part they install, so if if fails, they will replace it with no charge to you.
But if you don't care about the warranty and you simply must carry in the part, then buy it through the dealer. At least that way you're putting in the best part there is.
Hope that helps.
