I recommend everyone listens to a talk by Kamel el Makki titled "How to get a shahadah in 10 minutes." It should be available online somewhere, I'll try to find it inshaa'Allah. Obviously it doesn't garuntee that you'll get a shahadah after speaking to a non-Muslim for 10 minutes. However, it gives you tips on how to approach them and what to say when you have such little time.
