To get money from computer work you usually can work from home in your own time. Depending on how much time you put in, you could even make a full time income with some types of work. Many people do just that and it is not surprising because of the leverage afforded by the Internet.
It is rare to find online work in terms of working in a job. Getting an hourly rate is difficult to verify, so you may find this type of hourly paid work very difficult to get online. There are two sides to every coin though and the bad news is actually good news. You will be paid a lot more for effort expended.
