Can I copy the full system and layout etc

I have the task of manually setting out hundreds of androids a week and I would like somehow just to uploads all the settings and layouts, including the shortcuts, icons everything. Is there a way I can copy one finished device and download in on to all the others.

Hi, can you give us more info please - why are you setting up so many phones? do they all have a generic Google account or are you setting up multiple accounts?
