Just start writing. You aren't an expert until you start proving your expertise. It costs almost nothing to start your own blog. Be helpful, be present, be relevant. It takes time to be recognized as an expert. Answer questions in a helpful way consistently. Eventually people will remember you and ask for your input instead of you self-publishing. It's not like there's a list of opportunities. That's not how publishing works.
