Design template PowerPoint slides for company presentations

We’re looking for a talented PowerPoint designer to create a professional, modern, reusable PowerPoint slide template for our cybersecurity brand, RootSec. The goal is to have a polished presentation system that we can reuse across client presentations, technical reports, training, talks, internal documentation, and other cybersecurity-related content. The template should match the existing RootSec website branding (https://www.rootsec.me) and visual identity, rather than looking like a generic PowerPoint template. Ideally, we want a PowerPoint template (.PPTX) containing a wide range of professional and reusable slide layouts. For context, these slides will be used to present at various cybersecurity conferences, so having a brand identity is crucial. The idea is that when creating a new presentation, we can simply pick the appropriate layout and drop our content into it. Please create variations such as these below. I don't need EVERY single one of these, but a small selection, so that we can use and build our own new slides off of them: Title / Introduction Slides Cover/title slide Section divider slide Chapter/introduction slide Title + subtitle Title + large visual Text-Based Slides Title + single paragraph Title + two text boxes Title + three text boxes Title + four text boxes Text + highlighted callout Text + key takeaway Quote / statement slide Terminal/code-focused slide Before/after comparison Risk / impact / remediation layout Image-Based Slides Table layout Closing Slides Key takeaways Recommendations Questions / Q&A Contact slide Thank-you/end slide The most important requirement is that the presentation should feel like RootSec. The design should ideally be: - Modern - Professional - Technical - Cybersecurity-focused - Clean and relatively minimalist - Visually interesting without being cluttered - Suitable for both technical and business audiences - Consistent with our existing website branding Please use the RootSec website as the primary design reference for colours, typography, spacing, visual language, shapes, accents, etc. At the same time, we don't want every slide overloaded with cybersecurity clichés such as random hacker imagery, neon code, padlocks, skulls, etc. The design should feel like a credible professional cybersecurity consultancy/technical brand. A nice clean dark mode essentially. The templates also need to be reusable. We should be able to create an entirely new presentation from the template without having to manually redesign every slide. Please include examples of PowerPoint templates or presentation decks you've designed previously in your proposal. We are much more interested in quality, consistency and thoughtful layout design than simply having a huge number of slides. The budget is flexible, so it's not a fixed price.
