Power BI Dashboard Enhancement

I have an existing Power BI report that currently reads live data from a Google Sheet. The core dataset and basic visuals are already in place, but I want the dashboard to feel sharper, run smoother, and guide users intuitively through the insights.

The two focus areas are:

• Visual Design
– Apply a refined custom theme (brand colours, fonts, and consistent styling).
– Re-work page layout and navigation so users can find key metrics in as few clicks as possible (think buttons, bookmarks, drill-throughs, tooltips).

• Performance Optimisation
– Review the data-refresh connection to Google Sheets.
– Streamline any heavy DAX, visuals, or unnecessary queries that slow rendering.

Deliverables
1. Updated .pbix file with the new theme, layout, and performance tweaks in place.
2. A short hand-over note summarising the changes, any DAX improvements, and recommended refresh settings.

Everything must stay fully compatible with the current Google Sheet source—no migration to other databases for now. If this sounds straightforward for you, please outline your approach and an estimated timeframe when you reply.
