Must respondents represent an established institution, or could it be an individual or group of people getting together for the purposes of responding to the proposal?

It could be any of these things, but we will be looking for a good track record at building similar kinds of sites, and we will want to feel confidence that we can trust the respondent to accomplish what they say they will do. We will be able to issue payment checks to an individual or an institution, but if to an informal group there needs to be one person to whom the check is issued and they then disburse it.
