Try to find projects on freelancer.com/ upwork. The competition is fierce-- especially if you are just starting out with no portfolio and previous client testimonials-- so when you apply for a project write a stunning a proposal that punches the employer in the gut. Two years ago when I started out I was in the same boat as you, I applied for at least two dozen projects never heard back from them. Then I started changing my proposals, I wrote personalized proposals for every client to convince him/her why I was the perfect contract for the project. My very first client was an Australia based video production agency, they were hiring for admin assistant. I started my proposal with Aussie jokes. It clicked. I got hired. That's how I slowly built my portfolio.
