How do I get international customers?

Hi everyone,

I run a web design agency in Addis Ababa, Ethiopia. I am curious about opportunities outside Ethiopia, I have landed some works before through word of mouth. But I want to find a regular channel. What are some ways I can do this? Thanks.

P.S: I am redesigning my website with CSS Grid so there might not be much there. I am saying this because I know some of you would suggest a lack of portfolio etc on the site. Thanks again.
