Unfortunately it's not as easy as that.

The IRS has guidelines on who is considered an employee. If you set their hours, provide equipment for them to use and there's a few other things I forget, they are a de-facto employee regardless of how you pay them: 1099 or W2. This is why a lot of larger companies will not employ sole-proprietors directly. They require you to either go through a contracting company or set up some corporate structure so that you can't claim to be one of their employees.
