Why should you have to tell them what type of evidence to ask for? Let them show you the best evidence they have. If it's not good enough for you, explain why, so they can try to come up with something different that won't have the same flaw. Just make sure your reasons are logical.
But really, I can't imagine what it would take to convince me. Something big and obvious, unlike any of the "evidence" (and I use the term loosely) that Christians usually present.
