Can I repair my Power Button after dropping the device?

Hi,

Some times ago my iPad dropped to the floor.

My iPad Power button is now partly broken. It still works but I have to press it twice or so. And sometimes when I'm using my iPad the iPad goes randomly into standby. I found out that it happens by pressing the upper right part of the screen, too.

The back metal cover of my iPad is now slightly bent by 1-2 mm in the upper left corner (under the power button).

Could someone help me? If you need photos tell me.
