make some money

What are some easy ways to make quick money?

Yeah, so I’m planning a trip in December, and I am trying to save my money and stuff so I’ll have some extra spending money. So what are some things I can do to make some cash?

So far, I’m just recycling cans and saving spare change for the Coinstar machine, but what are some OTHER ways to make quick money? And don’t say stupid things like prostitution or donating organs.
Yard sale would work. I think I might be too old for lemonade stands though. Haha. XD

Garage sale? Just sell the old crap you don’t need.
I’ll edit if I have any more ideas.

Edit: Check out this link. It has some pretty good ideas: http://frugaldad.com/2009/05/09/quick-ways-raise-cash/
