When all else fails, try the direct approach. Contact the sororities yourself. You already have your packet together.
Excerpts from the LSU 2010 Recruitment FAQ Sheet:
How to Obtain Recommendations:
"2. Women who may not know of anyone in the area who is an alumnae member of a particular sorority should contact the national headquarters to inquire about a local person from their organization who coordinates their recommendations/references.
See national organization website addresses.

"4. What if I still don’t have a rec for all 10 sororities? Send enough copies of [your resume and 2 pictures] along with a note saying which sororities you need recs for to our address (472 LSU Student Union, 70803) and we will share your information with the sororities. It is ultimately the sororities’ responsibility to get recommendations for you, but it makes it easier on them if you do as much as possible to obtain them."
"The responsibility for providing letters of recommendation for potential members rests with the chapters (NPC Guidelines). In the interest of time, it is helpful to be proactive in this process.
Again, although not required, it is highly recommended to secure recommendations/references for the sororities."
