I agree so much with you Apples and Bananas. I am (I'm sure) the highest price home daycare provider in my area........... (and I don't even charge that much!) But I do a little test with all new potential families.........if one of the first three questions is how much do I charge then I politely tell them that I am sorry but at this time I have no available spaces to fill your childcare needs.
If they are only concerned about the bottom line then usually they don't care too much about quality of care.
I understand everyone has a budget in todays financial hardships but to be soooo concerned about price is a big red flag I've found most times.
