Can carry 6,000 lbs and the cost of $1,000 per flight hour total isn't a terrible price, it's far more expensive than just putting the vehicle on a truck for delivery of course.
Oh, I didn't say/mean that it had to be a quadrocopter/multi-rotor vehicle... I was just saying that it'd be a pretty large vehicle. While it's a cool idea, I suspect that a lot of people would be very wary of something of that size flying around their house/building without a human pilot onboard. It's basically the "not in my backyard" syndrome.
Here is the existing unmanned heavy-lifter.

The way those rotors cross are insane.
The BlackHawk unmanned system has been in testing for several years also.
