I love that you actually have a degree in elementary ed - that's awesome for an in-home provider! You also bring a lot of other things to the table with the languages and interest in arts. It sounds like you have a great resume to work with children as opposed to 'hey I have a kid and I want to stay at home, so I'll just 'babysit' other kids'.
I might be a little off the mark, but if I ever decided to go with an in-home provider I could not imagine paying any less than $10 an hour. Quality childcare is so tough to find, and let's face it, this caregiver is going to be spending a WHOLE lot of time with the children and teaching them so many things.
