I don't know what you're so worried about. What's to stop anyone in the office from running away with your code? I mean you could have some problems if you're hiring in China or Russia - but even then most of the time people just want an honest, steady job. Your source code is not usually something that anybody else wants, it would be almost impossible to find a buyer.

If you're really worried, just stick to people in developed countries with a sane legal system. But honestly finding people with great communication and technical skills should be a much more important criteria to the success of your company. You're company is much more likely to die from self inflicted wounds than because someone sold your source code to a competitor.
