I freelance full time. Sign up for TopTal or Gun.io - if you're good you'll get work immediately. The rate is up to you but likely somewhere between $50-$100/hr. I'm on both platforms and see jobs every week for React. Some are full time, others are 10-20hrs / week. You can even continue on the side once you get a full time job. I get LinkedIn recruiter messages every week and most of the time the rates are terrible, so haven't had much luck there. HN seeking freelancer also has contract / part time gigs occasionally.
