Marketing dashboard platform

I need someone to build me a marketing dashboar the can be connected to DSP platforms (programmatic advertising platform) through a REST API. As an agency, we have clients running advertising campaigns on some platforms. We would like to offer to our clients a personalized and real time dashboard where they can access with a login and password and see the data of the campaign. The idea is to host this platform on out website. So, our clients put their credentials and have access to updated digital marketing reports. So, first we need a amazing dashboard template. Then, we need it integrated with the DSP through REST API. The dashboard must also be able to generate graphics from excel, google sheet and allow images, videos and gif insertions. We need also be able to create different dashboards to different clients (1 campaign on DSP = 1 client = 1 dashboard) and allow each client access their dashboard with personalized credentials. For reference we are talking about something like this, but a little simpler: [login to view URL], [login to view URL] less
