Those are all I think I'll need by Saturday. I don't even know if I'll need them all, but it's ideal. They're in order of importance, so start at the top and work your way down, if you don't get through it all that's fine, I can make do with what you manage. I'll get you references for the rest when you're further through these ones.
Lemme know when you want the money sent over and I'll do it ASAP.
