I want to write a freelance article on a specific topic, and am getting ready to write query letters. I know it’s important to give sources of where I would be getting my information and people I can interview. Should I find and contact possible sources prior to writing the query letter so I can give specific names of people, or just generally say “I am planning to interview doctors specializing in…?” Which is better and more effective? I’d love some advice from successful freelance writers, if possible. Thanks!
