straighting a bent sub frame
 

was laid down and is now cocked, any ideals on where to begin with this?

you can see where the seat mounts that part is pushed off center half and inch maybe less. anyway to fix this with out paying a garage?

The picture looks like the near rail is bent lower than the far one. Maybe a picture from over head and from the rear will show the issue better. Put a straight edge where the problem area is to highlight it. You may be able to use a large prybar to twist the subframe closer to normal.
