Asking a provider for a duo?

Delete if not allowed

Is there a good way to ask a provider if they will bring a friend if it is not listed on thier ad?

Yes there is. "I'm interested in a threesome but see you don't advertise it. Are you amenable to one? If so, do you have a friend that could join us?"

That sounds like a very excellent and polite way to ask.
