Maximum number of Connections, Projects, Looks and Dashboard

Hi ,

I tried to drill down through the documentation but could not find.
I looking for maximum number of Connections I can define to BQ, the maximum number of projects, Looks and dashboard I can create in Looker.

we have a use case of building reports for clients where each client will have their respective database,
Also, is this a viable use case of Looker to deploy these kinds of solutions?
