How do I protect my idea for a new e-business?

I am working on developing a new online startup company, but I will be farming out certain aspects of the web programming to an outside source. I lack the technical knowledge as well as the time, and figure the easiest way to go about this is to hire someone to do the programming. I am concerned about my idea 'leaking' because of this, however, especially when I seek quotes for the job by posting the details about what I need done. Is there a way to protect my idea--not a product, more a concept--beforehand? This seems a gray area to me, and perhaps I'm being more paranoid than necessary, just want to keep things close to my chest for now.

I can give you some great advise on protecting your idea ,but first tell me a little more about it.

DON'T TELL ANYONE. DUH!!!!!!!!!!!!!!!!!!!!!!!!

Make them sign a confidentially agreement before any work is done.

Before sharing your information with anyone be sure to develop a business plan. This will formally document your business idea. Areas to include will be a detailed description of your product or service. Who the target market is. How you plan to advertise the product or service. Key components such as funding, suppliers, distribution channels, price, expenses, plans for growth, competition, location, and so on. Document as much as you can and have it notarized at your bank.
Before hiring anyone, be sure to formulate a contract with a disclosure clause limiting their ability to use any software, or literature they develop. Remember to get references for any hirees as well. A. Johnson WealthTransfer.bb2k.net
