Yes, don't you keep copies of your own website contents?
You mean neither your web hoster or you have copies of your page codes and images etc? That's not good.

Perhaps if you have nothing left, you can use the WayBackMachine archives to view your old pre-hacked pages, and then do a right-click "view source" on each one and copy the code and paste/create new pages from that?
