Some of the sorority websites (the HQ websites, not the local chapter) will have a recommendation form that the person who writes you a rec will download and send in to the chapter. When my older daughter went through recruitment, I looked at all of them that I could--some are not available without a password, but a good number of them can be read by anyone. This gave us a good idea of all the information that should be put on the resume to make it very simple for the person writing the recommendation.
The custom in our area is to have your mother write a note or call asking if the person would be willing to write a recommendation. You then follow up with a packet that includes your resume, a stamped envelope addressed to the chapter, a photo (usually leftover senior pictures), and a note thanking them for writing a recommendation (in our area, this note is from your mother). Then, two or three weeks before recruitment, you sit down and write thank you notes to all the people who wrote the recs, tell them how excited you are to be going through recruitment and off to college, etc. This also serves to remind them to do it if they haven't. Then, after bid day, you sit down and write notes to all the ladies who wrote you recommendations and thank them again, tell them how much you enjoyed recruitment and tell them what house you pledged.
