what are the typical hours of an overnighter with a provider?

thanks

They vary from girl to girl.
You should ask that question of them .
I have seen some post something like 7:00 pm to 7:00 am.
It doesn't hurt to ask them, and state it as you have here, no one should be put off by it.

Each provider's time depends on the $$$, which is unique to each individual. So best thing to do is email and ask the provider.
