Don't give up, keep applying. It can take a while to land your first job. In my first 3 months, I only landed 4 clients and they were small starter jobs.
I had a look at your profile. Your skill is worth more than $5 an hour. I know that works out more in your country than it would in the USA, for example, but the majority of clients are based in the USA and they will think $5 is cheap and cheap doesn't usually equal high-quality in many people's minds.
Your profile bio does have a few grammar problems. I know English is not your first language and to be honest, I've seen worse bios, but you may want to get someone to have a look or use an online grammar checker. Mainly because the majority of clients are English-speaking.
Hope that helps,

Upwork has a million people like this.
Be something more, or be something different.
if there were a million waffle bakeries in your town, and you wanted to open a new restaurant... would you open up another waffle bakery? Or would you open up something different?
I would try not to start every sentence with "I" (clients are not interested in who you are, but in what you can offer them) and I would do without your opening hours. This is a global platform, people just don't all have the same times as you. Don't worry, I work with people in all sort of countries, I know when they are available and leave messages for them when they are sleeping.
