Because I was "too busy to bother", I'd just ask my current employees if they had any friends that needed work.
Someone always did, so I'd say, "Tell them to start tomorrow morning. $10/hr. Show them what to do." And that was that.
To be fair, this was a mail-order CD store, so most of my employees were in the warehouse. But I even did this same approach when I needed a CTO. ("Anyone have a friend who's good with Linux? Yeah? Is he cool? OK - tell him to start tomorrow.")
But maybe that they were friends-of-friends helped with the trust part.
