dang, looks like I didn't get to you in time. I was fixing my own car...
The easiest way I've found is to put all the accessories back on, and all the pulleys... put the belt back on... and wedge a BIG ol' screwdriver into the power steering pulley. Wedge it so it won't move counterclockwise.
Then, crank away.
If you don't want to do that, then get a big ol' breaker bar (or pipe over a breaker bar), lay it on top of the subframe (the pulley is going to rotate clockwise) and attached to the crank pulley bolt, and bump the starter. Please make sure the battery is hooked up, and MAKE SURE YOU DISCONNECT THE DIS!!!! It would be absolutely DISASTROUS if the car actually started. The starter has a shit-ton of torque and should be more than plenty to break the bolt.
