Upgrade and Refine Existing Wikipedia Page

We have an existing Wikipedia page that needs updating and cleaning up. Looking for someone experienced with Wikipedia's editing standards, not a beginner or someone new to the platform.
What needs doing:

Update outdated info in the article (including infobox details)
Add recent achievements/coverage with proper independent sourcing
Fix any tone issues so it reads neutral, not promotional
Resolve any existing maintenance tags/flags on the page
Proper citations using reliable, independent sources
Full compliance with Wikipedia's paid editing disclosure rules

You must have:

A real track record, share links to live Wikipedia pages you've created or edited
Solid understanding of notability guidelines and neutral point of view policy
An established Wikipedia editor account with real edit history (new/low activity accounts get flagged fast and we want to avoid that risk)
Good research and writing skills

Please don't apply if you're offering "guaranteed" results or can't show real examples of live pages. We've been burned by that before and won't go that route again.
To apply, send:

Links to Wikipedia pages you've personally edited or created
A short note on how you'd approach sourcing for this project
Your estimated turnaround time
