Question about contacting JV partner

Hi Warriors,

I'd love to hear your ideas on what to ask your jv partners when you've just started contacting each other.

I've sent about 30 JV proposals during the past two days, and have received one reply from them showing interest about this deal.

I told her that I look forward to working with her, but since the sales page is still in pending status, we'll have to wait for a while before the promotion.

That was all I said. However, there're one thing that I'm not sure whether or not I should ask.

Should I ask her list size?

If not, what are the questions that I SHOULD ask her at this stage to have a better understanding of this particular jv partner?

I'm not having a huge launch, so I guess legal stuff won't get involved too much here.

I'd appreciate anyone to share some past experience on how to communicate with your to-be jv partner when he/she has shown interest in your deal.
