Nick Jonas... when and where?

I am absolutely in love with Nick Jonas,and the rest of the Jonas Brothers, and i wanted to know how i can find out when they have meet and greets. I would practically kill myself to meet any of the brothers (preferably Nick). I have loved the Jonas Brothers for so long and the closest i have ever been to them is at their 2009 concert when they walked right pass the door. It is on my bucket list to meet one of them. I would be the happiest luckiest person in the worlddddd! Please let me know when and where can meet them i live in Ohio so i would really love it if were around this area(:
