BOY, appears that 'something' quite heavy and pointed fell on the device - any more details - might help? Of course, the question is 'how much' internal damage was done which likely could be determine only by opening the iPad by 'someone' w/ experience in repairing these devices. Just a few more questions - is the case deformed and does it come on?
In the meantime, take a look at the appropriate
iFixit iPad 2 Manual which will give you some idea about the complexity of the repair (i.e. just replacement of the glass and other layers) and the cost estimate; if you're not a DIY, then an assessment by a local reputable Apple repair service would be my only other suggestion. Good luck - Dave
