Integrating Kobo in my solution workflow as a Survey tool

I would like to use Kobo as a survey tool as a option in my solution primarily to create surveys, with different user level access, dashboards based on data collected in real time, again role based. The data being collected will be proprietary hence will need to reside in our servers.
Can you help me understand what would be the type of Kobo offering that will meet this requirement and what would be the costing of the same.

Welcome to the community, @meethaz! Did you mean you wish to assign certain permissions to users with whom you would like to share your project?

Yes, role based permission. There can be a survey creator, survey approver, survey conductors who do the surveys on the ground and put in the data and relevant dashboards for all the roles. There could be more roles but there are bare minimum in my use case.
