Converting business presentations from PowerPoint into Keynote

I am looking for a meticulous person with an excellent eye for detail, and some Keynote design skills.

I have four presentations used for new business outreach by our startup that currently exist in PowerPoint format. I would like them to be converted into Keynote, with license to tweak the design of the slides slightly to make them more impactful.

Attached is an example of one of these presentations as a PDF. In total there are approximately 150 slides of content across the four presentations. The Keynotes created must be compatible with Keynote version 13.1, running on MacBook Air 2017 (macOS Monterey).
