French w/ Quebec flavor?

Hey guys, trying to say: "so whenever's good for you" (implied: is good for me/ we can meet), or "any time after that is fine/cool" in French, hopefully with a bit of Quebec flavor if that could at all be worked in. (It comes after my having said: I'm available after 4.)

I'm unsure on the whenever (n'importe quelle heure?), the many ways I could choose to say good (est bon? va bien? something else?), and, God knows, the Quebec thing (any tack-ons or vocab choices that would make the sentence sound like someone from Quebec rather than France would say it?

Thanks!! :D
