Good day! I have written whitepapers before, and I have covered some fairly technical subjects. My ability to help you will depend on what type of technical topics you hope to cover. I'm a good researcher and can usually handle new areas, but if I'm unclear on the subject even after researching, I would avoid that project.
Technical topics I have worked on include architecture, civil and industrial engineering, cybersecurity, food provenance data tracking, and more.
Finally, I am a text-only writer. Formatting the whitepaper with infographics etc. is up to the client.
Regarding prior work, this may be somewhat problematic. I've been published in a few technical magazines and journals, but that was decades ago. Since then, I have ghostwritten most work, and even when NDAs are not required, I assume that disclosure of authorship is not preferred. Besides this, since the work is published under other people and businesses' names, you will have no idea whether you are really looking at my work.
If we appear to be in agreement that my service might suit your needs, I would be willing to attempt a section of a white paper for evaluation purposes. And, since I (and presumably you) feel that outcomes-based pricing is preferable, I could use a sample to determine what you might expect in terms of cost.
Regards
Andrea
