i want to start a sorority- help me

I wish to start a sorority in my school but i am not sure ho to do this. There is one other sorority in my school, but we do not wish to be a little sister chapter to them but we wish to start our own. I'm puzzled on how to start my sorority. How do i pick a name? any special requirements? how can i keep control over my group if we start a sorority? h many people should be in it for a first year? Help me... i would really like to start one in our school....but we/I need help from people who are in sororities. help us!
