Siero Media Powerpoint master slide presentation

We are looking to create a brand-compliant professional powerpoint Template (with a comprehensive set of master slide formats) for our company, Siero Media. Siero Media orchestrates and produces, for our clients, transformative, impactful internal and external communications and podcasts with power of storytelling.
Please view the Siero Media company website via the link and use the look and feel of the website as a guidepost for designing the PowerPoint template master slides. We also have the following brand guidelines for you to use.

If this aligns with your capabilities, would you be interested in and available to support. If so, can you please let us know the following?

Are you willing to sign an NDA for this work if needed?
A. How long will it take to provide a preliminary quote for a template with a comprehensive set of master slides?
B. Please provide the estimated time (in business days) it would take to create an initial template for review once the design elements have been communicated and received.
What is your pricing for this work?
Can you deliver on the following asks?
Slide master – One color (black background) full suite of master slides
Slide master – One color (white background) full suite of master slides

Other guidance:
We would like the font for the powerpoint to be something readily available on computers (that we won’t need to download/install individually)
The sample powerpoint is NOT what we want this new powerpoint to reflect, we’d love for you to be creative and build off of that.
We want the powerpoint to be clean, relatively simple, and brand-compliant.

Will you need other information or materials to create the powerpoint?

Thanks!
