As long as you master the skill of designing websites, try to start designing in Upwork & Fiverr.
So, you will improve your skills. Then you can deal with clients in your country by building a very unique and personal website.
If you can send me a unique website, even if it is WordPress or SEO with add-ons, software, and contains many pages, I can provide you with other business ideas.
Moreover, you have to invest in other skills in the same field, such as programming applications and transferring websites that you have designed to applications. So basically, keep mastering skills one by one.
