Legit but Quick Way to Earn Money Online While Helping Others?

If this question is not allowed here, please send it to /dev/null and accept my apologies. But I think others might find the discussion helpful.

I suddenly find myself without a job. I'm actively searching for new opportunities, but got wondering about ways to generate some income in the meantime.

I'm NOT looking for a "get rich quick" scheme, but rather for ways to legitimately, legally, morally, and ethically turn skills and knowledge I have into money. And I need to do it quickly since the bills are coming due.

I can design and build web sites, for example, but that's not something with a quick turnaround. I also need to spend the bulk of my time on a "real" job search, so I only have a few hours a day to work on generating supplemental (well, primary for now) income.

I'm interested in hearing ideas on how to do stuff online that would...

> Generate income for me > Be quick and easy to set up > Involve minimal risk (of failure or money) > Actually be helpful to people > Scale well in case I'm able to get some serious traction > Be repeatable / multipliable so I can grow income fast

If, with the help of contributors here, I can come up with some workable ideas that prove successful, I'd like to write a free ebook so that others who find themselves in my situation can avoid some of the worry and panic I'm feeling.

Thanks!
