Pitching an idea?

I work for a cell phone company so I know a lot about cell phones. Well the other day in a company meeting I had thought of a great idea for a website to sell phones. This idea has potential to make so so so much money. How do I get a hold of an electronic company that sells phones to invest in my idea?

If it's truely a great money-making idea, I'd protect my idea using a Lawyer - ensuring the company you show it to would not be able to copy it if they turn you down...Good luck !!
