We actually just started another thread on this topic a little while ago. I posted some ideas on it.

I've spent a little bit of time talking with some of the other recruitment guys in our chapter, and they mentioned some good points.
1. Your chapter recruitment events should have their top priority revolve around getting to know PNMs you already met (because you should have already met them and made them your friend before you try to invite them)
2. Good events should reflect good goal-setting
On that second point; it was something that was mentioned to me a while back. Your number-one goal should be obvious based on the events you choose.
EX: If you're number one goal is to win the soccer intramural championship, shouldn't your events revolve around sports - especially soccer?
