Finding key person in Fortune 500 companies - 500 names - not a web scrape - deep cross referencing research required -- 2

This is not a quick data scrape job. I have an hour long video to train you in how to do this but it's not a data scrape. Please read below in detail and consider this before you submit a bid. For each of the Fortune 500 companies I'm looking for the main leader who runs talent acquisition. I have the list of companies. The good news is "Talent Acquisition" is in the job title of all talent acquisition people on LinkedIn, so we can start with the company name and the US as the location, and "Talent acquisition" in the "Title." The bad news is, there's no way of knowing who the real head is without doing proper research. I have recorded a video showing what it took me to get the first ten "Heads of" and there's no quick way to do it. Some of the largest companies have 250 talent acquisition people in the US, and many of them have the title "Head of" or "SVP" but those aren't always the main person. Only in cross referencing Google searches with LinkedIn searches, and reading the profiles of many different people at that company to figure who the real leader is, can this project be done. It doesn't matter if you've been a researcher for 30 years - you will have to watch my video to really really understand how to identify this person. I'm not looking for someone who will watch 5 minutes of the video and go, "Yeah I know what I'm doing." I'd like to watch it and really get it before you start and then be committed to quality over quantity. For the one who does a good job, there are tens of thousands more people I need help finding. I don't want to have to check through every single one as otherwise I am just as well to do the work myself. I want someone who takes pride in excellence and who will get this project and work confidently knowing they've got the right people.
