Wrong time of year....why don't you wait until spring and D.I.Y.?
It's a nice easy job to do and is very rewarding if you do it yourself.
Iv'e done it on most cars that I have owned and I have enjoyed every minute of doing it.
All you need is a bit of patience, some good quality sand paper/Wire Brushes/ etc. and a bit of L-Bow grease.
If you want to DIY this time of year you can remove one wheel at a time and bring it indoors to do it.
Providing the Missus doesn't mind an alloy wheel on the kitchen table?..!
