I've got an idea for a product, what to do next?

[theboyfold]

Just this lunch time I've had an idea for a piece of software that could be useful to major businesses.

Now I've had the idea and realised that I don't have the skills to develop it myself I'll need a developer. Which is easy enough, but how do I protect myself from having the idea taken away from me by said developer?

Also how do I go about approaching the companies with an idea?

Sorry if this is a little vague, but the learnings of what fellow PHers have done when they have taken an idea and run with it would be useful.
