And I assume your door is fixed by now?? If not, see below:
We had our front door replaced a few years ago. Go to a small door hardware store, like the previously mentioned San Gabriel Sash and Door. If they don't hang doors, they will likely have several business cards at the contractor's counter of door installers. They counter guys may even be able to direct you to a good installer. That's how we got our door installer, and we've even brought him back to swap out several windows.
And if you're looking for a good looking wood door, see TM COBB Doors.
