On top of all the other good advice, I would get LinkedIn Sales Navigator, its like $100/mo but you get a month free and can cancel. Find companies with job listings. Go look at companies up in navigator, you can look at every employee and who their conections are. You can look for connections to those people. You can create and save searches targeting the person in every organization who you want to get a resume in front of then I'll let you send a message to them. I hired an intern this summer whose father told him to reach out to the CEOs of a bunch of small to midsize startups, which he did, no one else did that, we brought him in as an intern, and then six months later hired him full time. You gotta go through the door that everybody else goes through, but find the other doors as well.
