All people who want to start an online business or find work online often underestimate their skills. They are afraid of making that first move because they aren't sure there is anyone who can hire someone like them. After all, you need to convince someone that you can do your job well enough and if you don't any experience, then it would be hard to convince this prospective client that you can deliver what they want.
The fact though is there are plenty of small business online whose budget doesn't permit them to hire people who will work for more money than they can afford to pay. And these small businesses will for that reason hire anyone who is new to freelancing because they initially won't charge much for their services.
Everyone has to start somewhere. You've heard of the journey of a thousand miles . . .
Regardless of the little you make when you start out as a freelancer, don't mind. As you gain experience, you'll start earning more money.
