I would like to see metrics from this company on ROI and success levels of previous similar campaigns.

This is a reasonable request. I will inquire for previous campaign results examples.

How are they proposing to work with Hive to obtain the required information? It is not possible for one individual to be feeding them information because this is just beyond the capability of any one person.

I am very flexible :).... but yes, including interested individuals as well as using group participation will be important when it comes to a robust proposal as this.

Press releases must be carefully crafted and vetted to make sure there are no issues.

Yes.
