OK the guy wrote back and it looks likely that we can have some.  How
many? 900 is an awful lot...

Mitch: 200?
Daniela: how many would you use?
Michael: how many for you?

anyone else have ideas?

I'd like to get back to him later tonight, or tomorrow at the latest,
since I took so long the first time around, and ideally I have a number
to ask about.

Reasons why we should ask for all of them are also acceptable!
