Need Help with Rush and Retention Issues

[Industrial11]

I'm part of a local sorority on a small campus where the ratio of men to woman is very small and almost non-existant at times; and my sorority has fallen on tough times as to where we can't seem to recruit girls. Me and my sisters are very close to eachother, but we need to expand and we need to do it sooner rather then later. We have around 6 girls graduating May of 2013 and that is almost of all the sorority. We all really small and never seem to be able to get our numbers up above 10. Idea's for Rushing, and Retention of PM's would be great advice for us. Anything and Everything is helpful I would love to see our numbers grow in the next two years that I'm on campus.
