OK. I would recommend trying to get it into recovery mode, which might allow you to restore it using iTunes:
1) Turn your iPad off.
2) Press and hold down the home button.
3) Plug your iPad into your computer whilst iTunes is running.
4) Release the home button when you see the iTunes logo and a charging icon on your iPad screen.
5) Your iTunes window should have a button that says Restore Device. Click on that, and you are pretty much done!
Hope this helps.
