IPhone help? Its cracked and locked up and buttons don't work?

I have an iPhone that is locked up because of unknown password, neither buttons work and screen is cracked really bad and it won't connect to iTunes to reset. Any info on how much it would cost to have this stuff fixed? I can replace the screen myself but does anyone know how I can get into it?

Cool
