What is the website where you can bid on jobs?

I know I've been there before, but I can't remember the name of the website(s) where people/companies put up jobs they need done (eg. programming/electronics) and others make a bid for the work. Can someone remind me please?

Not necessarily Arduino, and this is for a friend of mine, not me personally.

a bit of everything there

Geographical boundaries?

In this particular case the fellow is Australian, however I'm assuming you could write code for (say) the Arduino for anyone on the world, so the boundaries shouldn't matter too much. And if making a physical device was part of it, you could mail it. I would assume however that he speaks only English.

Indeed I live in France but 80% of my client base is in the USA. I write code, talk over Skype and send prototype hardware in the post. It works well for me.

Cheers Pete.
