2004 Audi S4 Question Wheel Bearing Replacement Cost

Hey guys,
Thanks for taking my email!
I have a 2004 Audi S4 Cabriolet, 4.2L V-8 Quattro
My driver side(left) rear wheel bearing just blew out.
What should I expect to pay from a non-audi dealership.
I've seen the part itself go from $35-$95.
I do live in an expensive COL area, washington DC!

Thanks-

Ed
