I can't answer most of your questions. Buy will give you my
Your dogs seem very reasonably priced. I would start by trying right here on YT in the dogs for sale forum. This is where you know people are seriously looking. Post pictures for sure. I found our little Jill via the classifieds in a large publication newspaper in our state and only ended up driving 60 miles to get her. Certainly the Indianapolis Star would get you lots of exposure.
We had to go for an interview with our breeder and they were very comfortable with us after meeting us. We did get a health guarantee. Also, a clause that when we get her spayed and provide proof, we will receive a $200 refund.
Good luck finding forever homes for your little furbabies!
