Breaking Dawn

I'm working on finding a way to contact Rene Haynes, who casted extras in both New Moon and Eclipse. I want to know if she's casting Breaking Dawn too: I desperately want to be in Breaking Dawn. I preferably want to be Irina (She's the one who sees Renesme and tells the Volturi, she's from the Denali clan) or Maggie. (She's the little red head from the Scottish coven who can tell if someone's lying) I found her email address, I'm just debating whether to email her or not. I'm thinking of saying something like,
"Dear Rene Haynes,
Hi, my name is Natalie and I'm a huge Twilight fan. You've casted both New Moon and Eclipse, and I think that you did amazing. I wanted to know if you were casting Breaking Dawn also, and if you were, what the chances are that a young teenager with experience in acting could be in it.
Thank you so much,
Natalie"

So whattaya think? I think it sounds pretty good, but that's coming from the person who wrote it. And I DO have experience FWI.

Rawrg, I'm so confused...
