get a big plastic pan stick it under the car and find the radiator plug under the car...pull it and let it drain then look in the owners manual and fill it according to that.

50 bucks doesn't sound too bad, I might take my car to a shop so they can do it.

I don't flush with tap water because of the minerals in the water. I use distilled water. Learned that with water cooled motorcross bikes.
