What have you done to get started on this? Have you analysed your source data? Have you defined your metrics & dimensions? Have you prepared mock-ups of how you want to display the data? Have you got the images that you will probably need?
If you don't know where to start, I suggest that you consider hiring a consultant to get you started.
Data association is something considered heart of Qlikview, If your parameters are your dimensions, then your dashboard will automatically change when you select or filter your dimensions thorough data association defined in your data model.
