Online jobs for establishing credit?

So I need a job. Really need one. I’m almost 20 and have yet to be employed.

The big problem here is school. I attend a university daily for rather ludicrous hours.

Although I physically need to be in class 24/7, I barely do anything in these classes. Giving me a lot of free time with my computer.

So as the title says, I’m just wondering if there are any online employers that can help me establish some credit and get some work experience under my belt. I honestly don’t care what the pay is. I’m not looking at this job for mainly money.

And yes, I’m doing local and google searches as well. Figured I might as use all my resources.
