Business Proposal PowerPoint Design

I already have a full set of reference images that outline the flow and rough layout of each slide. I now need those visuals transformed into a polished, editable .pptx deck that I can present as a business proposal. The tone should strike a balance: formally professional while still feeling creative and visually appealing. Clean alignment and consistent spacing matter to me on every slide.

Key elements to build in:
• Graphical charts and graphs based on the data I provide
• Custom icons and illustrations that match the brand style and reinforce key points

Colour palette, typography and overall look should follow the references I send, yet remain fully editable (no flattened artwork). Please set up proper slide masters so future edits are straightforward.

Deliverable: the final PowerPoint file (.pptx) with all fonts embedded and any linked assets neatly organised in a separate folder.
