Recs?

[S_A_I]

So, I have been trying ALL summer to get recs. I've asked around at church, work . . . . I have found a girl who used to go to my church and who went to the same school as me was in a chapter that is no longer at my school, so she wouldn't be able to write me a rec. FINALLY, today, I asked a woman at work who said SHE was not in a sorority BUT a really good friend of hers at work was in one. She told me to give her my information and she'd talk to the woman at church. My questions are: Is it too late to get a rec letter? (Rush officially starts on Sept. 3) and What should I give the alum? Should I give her a resume and picture? And one more question : This is for people from a smaller greek system. The school I'm rushing at has a pretty small greek system (4 nationals and 1 local). That, to me, is small since I come from UTK which has like 14 nationals. Do I really need to worry about getting rec letters since the system is so small? I know at UTK, from what I heard, bids were rarely extended to juniors so you pretty much had to have a rec letter to not be cut 1st round. Any and all suggestions are appreciated! Thank you in advance!!

I know that it is not the PNM's responsibility to get a rec letter; It's the chapter's, correct? But, to my knowledge, there are no alumni associations in this area. Also, I like to do everything I can do beforehand so I feel a little bit better!
