Are there any paying jobs where you work on-line? If so is there a place where are they listed?

I am a parent with three small children who has just found herself in desperate need of employment. I cannot afford child care after school but can put more than full time from home.

Because I do a lot of volunteer web work and am very tech savvy I got to thinking “What if there are places one might be able to work on-line for people who are excellent in Photoshop, wordpress, forum building and forum moderation?”

Is a directory of internet jobs anywhere that someone could point to?

Do such jobs exist?

Perhaps I am just dreaming.

Thanks in advance for any input. It is most appreciated!
