Power point presentation based on company colour palate

We need a template for a presentation that includes text, tables and graphs. We want graphics that are compelling, inviting and communicative. Power point is old fashioned but its presentations do not have to be.
The output should be in a form that is close to client ready, editable by us and capable of being used as a template by us for future presentations and reports.
Output would be for brief presentations and Client Reports.
