Congrats on Bama, Kim! Get recs from your mom's friends and see if they have any friends in the remaining sororities you still need the recs for.
Also, send around an email to everyone you know, make phone calls, get a hold of mom's Christmas card list, etc. and let everyone know you got into Bama, you're going through recruitment and you need help with recs to the following sororities... you'd be amazed at how many women and men can connect you to sorority women! You'd also be surprised at how many of your HS teachers and admins are Greeks!!!
Definitely contact the Alumnae Panhellenic in the area closest to you-- even if it isn't in your county, they may be able to assist you by phone and email, or connect you with women in your area.
Good luck. Please keep us posted
