Exploring Unusual Ways to Monetize Editing Skills

I’ve been curious about creative ways to turn editing skills into income outside the usual freelance platforms. Most of us know about proofreading or copyediting gigs, but has anyone found success with less obvious avenues? Maybe editing scripts for indie filmmakers, polishing technical manuals, or even helping with grant proposals? I’d love to hear about any unique opportunities you’ve stumbled into or ideas worth exploring. Bonus points if it ties into niche interests I’ve dabbled in solar power docs and found that pretty rewarding. What’s worked for you?
