Formal Client Proposal Presentation

I need a polished slide deck that will serve as a business-grade client proposal. The deck must strike a strictly professional and formal tone while guiding the client through our value proposition, key figures, timeline, and next steps. You will take my raw notes (company overview, service packages, case studies, and preliminary numbers) and transform them into a clear narrative with clean, consistent visuals. I appreciate subtle branding—logo, colour palette, and typography that align with our existing identity—without turning the slides into marketing collateral. Think boardroom-ready rather than flashy. Core expectations • 12–15 slides structured around: introduction, pain points, solution, benefits, evidence, implementation roadmap, pricing, and call-to-action. • Elegant charts/infographics built natively in PowerPoint (no flattened images) so I can update figures later. • Master template and all editable source files on delivery. I will provide logos, brand colours, and rough content as soon as we start. Please share a couple of B2B decks you have recently produced that demonstrate a formal style and strong data presentation.
