Proper etiquette for approaching sorority alumnae?

[creditfortwo]

I am curious as to what the proper etiquette would be to approach sorority alumnae for letters of recommendation. I have a list of people (friends, mutual friends, teachers etc) and I do plan on asking them for recommendations or if they know any sorority women. However, when the time does come, I am not sure how to go about approaching the sorority women.

I went to the local alumnae panhellenic meeting earlier this year so I made sure to get everything in check(just not the alumnae lol). I have my transcripts, resume as well as many photos taken by photographers.

I'm not sure how to approach a sorority woman for a letter of recommendation. My idea of approaching would be to email them and provide them with an already stamped and addressed envelope. And then a week or so later I would send them a thank you note of course thanking them for taking time out of their lives to write me a letter of recommendation.

I'm not sure if typically pnm's meet up with the sorority women for a one-on-one meeting. I'm willing to do it. I don't mind meeting up at a restaurant or cafe and paying for lunch or something, if they feel a meeting is needed to truly get to know me.

But ultimately the power falls in the rec writers hands I'll do whatever is convenient for her.

Advice?
