ThetaPrincess24 attends (attended?) EKU and might be able to help. Best to PM her.
I have family and friends that attended Eastern as well and were Greek there.
Yes, yes I know, they are STILL Greek, but what I mean is that their undergrad chapters were at EKU. 
I'll see what I can find out but in the meantime, follow the advice already given. And start now!
Best of luck.
