Wanting a Milk Goat

I am looking for a nanny that is currently in milk.
Our family goes through about half a gallon a day.
My other milk goat went dry before we were quite ready for her to, and my other nanny is due for a February/March.
Prefer larger breeds such as Saanen, Nubian, Alpine, Sable, LaMancha, Oberhasli, etc, or a cross of any of those.
Open to possibly trading 3 young Nigerians Dwarf does for the right goat.
They are all about 1 to 1.
5 years old and have been running with my two blue-eyed nigerian bucks for spring kids.
One doe has blue eyes.
