Need advice on how to find clients (pls help)

I am mainly a full stack web application developer (not officially, but I am quite skilled in that). But I can also do stuff like SEO and I am working on copywriting.

I started this when I was 16, now I am 18 and in these 2 years I haven't made a single dollar so far. Main reason being I can't find clients.

I had gotten a client whom I happened to randomly text on Telegram but unfortunately he bailed out after we got midway through the project. I simply cannot find someone who is actually interested, I had no luck on Fiverr and Upwork or basically anything. Even Usertesting (which I got approved on April 1st 2021) has not even provided me with a single test so far, and UHRS has tests which get me like 3 cents.

Kinda frustrated that I haven't been getting anywhere so far.

So I wanted to ask if I were to start from absolute scratch what should I do to get some clients or to actually earn money(online only) ?

It would be great if I could make at least somewhere around $150 a month to cover my own expenses, but hey at this point I would take even $50.

Btw, I am based in India.

Thanks for your replies!
