I worked on a language learning site and in order to try to onboard tutors, I wrote a script that scraped the Preply tutor list, which gave first names, pictures, and a YouTube account link.
From there I made a spreadsheet and spent hours googling names and trying to match up pictures to faces, sending messages asking if they'd like to be a part of a pilot program on my platform.
Got quite a few people willing to try it out :) but sadly the startup didn't succeed. Fun times though.
