Also, do you have a recruitment resume yet?
Here's an example:

Create one & give/email it to alumnae who can write you a rec.
Also, check the Ole Miss recruitment thread -- there are some great tips on finding recs.
If you are contacting the individual alumnae associations, many will have websites. CALL the local contact person - that group may have an alumna who goes to your church, knows 1 of your high school teachers or college professors, has a connection to your parent - and can write you a personnel recommendation.
Post that you are going thru Recruitment at UT on Facebook and looking for alumnae recommendations. List every GLO (Greek letter organization). From 6 degrees of separation, you'll be able to find sorority alumnae!
