it sounds like you'll only be able to use an action for a portion of what you are trying to do. I would set up an action for the stuff before the crop and then after you manually crop, set up an ending action.
BETTER YET! do what I did, hire an intern from some local college to do it for you. Hey, it's experience and they'll go for it. Put an ad in the local paper. You'll get some calls.
