Nigerian Dwarf Dairy Princesses Wanted!

Looking for a couple pregnant Nigerian dwarf dairy goats in central Massachusetts .
I am allergic to cow dairy. I really need some milking goats that are ready to go.
I have some lovely old girls, but for some reason nothing worked to get them preggy and now at their age...
They are sweet. I don't want to be cruel to them. So seeking a couple of new ladies if pregnant even better.
I can pay for them. I can pay for stud fees for them if you can direct me because I still can't figure out why I couldn't get my old ladies pregnant....
Oh Gods, that came out sounding terrible..............
Anyway, help, I need some milk and some milkers that are not cows or over sized large goats.
