Rates are about the same around here. We have a Kindercare here and rates are similar, maybe a little higher.
Legal in home providers here charge $100-$175 from what I've found. I used to charge $130 and have had no problems getting families. I just recently raised my rates to $140 and have implemented that rate with 2 new families and am going to raise the rates for current families to match new families, in January. I get calls all the time at the $140 rate.
I agree with EntropyControlSpecialist, the minimum I would charge is $125, but I be you could charge more!
