I plan to do the exact same thing next year. I don't have all the answers for you, but I would start by asking my LinkedIn network about any contracting jobs <6months and build a CV website. I assume you come from the Tech industry, but a lot can depend on what branch of IT. Developers can get their name out a lot easier than (DevSec)Ops people by contributing to OSS, so give that a try. But either way even a basic Udemy course on the subject can be helpful if you have no idea where to begin.
