bumper repair...how much would do u think?

ok i'm such a turd, i already know this....
i wasn't paying attention when backing out of my buddies drive way and i backed into his mailbox and address sign (reflective metal sign attached to his mailbox with his address numbers)

Anyways now the bumper on the back of my 04 civic has about a 4-5 inch scratch in it...of course this is a year to the day that i got my car..so what a way to have its one year birthday.

I've never had to have any auto body work done so i have no idea where costs start at...
any ideas?

thanks
ryan

OOPS. Could have busted the light as well. That would have added some bucks. At least its just the bumper.
