Very cheap, you wont find anyone who can do it (properly) cheaper than that.
Bearings alone will cost you more than $250 without a trade, and you cant make the shims at home so that quote is a amazing. I wish i could find a place to do that price for my diff. Usually they want 400+ to move mounts.
Only possible way you could save an extra 5c is if you supply the diff housing and axles, ie buy it for less off ebay? any wrecker will want 200+.
