My experience has been the opposite. Best employees aren't desperate to work for you. They're gainfully employed, and you have to poach them. No one I know who is productive would give up this much time to something. Almost everyone I know who is unemployed and desperate would.
The key to finding good employees is to do what Google does. Find successful people. Don't have them come to you -- go to them. How do you do this? Talk to professors and see who top students are. Read publications and books in your field. Hire whoever wrote them. Find neat free software projects, and hire the authors. The list goes on. People like that generally won't want to work for you, and the trick is to recruit them somehow.
