How much for babysitting in my home?

I have 10 years of nannying experience and now as a SAHM to a 5 month old, I have been trying to babysit another baby from my home. In the past I got paid anywhere from 10-15$ an hour as a nanny but have been asking for $10 an hour now since it's from my home & I have my own child there. But people are asking to pay $20 a day for 8 hours of care or 3$ an hour! I have been waiting for someone who will pay $10 but am starting to give up. Is this normal for babysitting rates now?? 
*** this is not a daycare though, just a stay at home mom (former nanny) babysitting from my home. Just ONE child so there's not a lot of kids here.
