Door hinge options

Ok well about a week or more ago I forgot to put the jeep in park while I was on the trail and I turned the engine off. I had just stepped out of the jeep when I turned the engine off so the door was wide open, needless to say when the engine turned off the jeep started to roll down the hill. The door slammed against a tree before I could get it to stop, but I was lucky in that I did not break the glass. The door got messed up bad (4" gap at the top of the door) the mounting brackets got bent out and back. So when I went to replace the door I bent them most of the way back into place but found that one has a crack in it and the piece on the hinge that risticts the doors opining are both broke off. What are my options for new hinges since I would like to be able to take the door off in the summer time. Im almost broke after fixing the door so the cheaper the option the better.

Here is a link to another site where I have pics of the door when it was broke and after I fixed it (sort of). http://www.marylandjeepclub.org/phpBB2/viewtopic.php?t=6903
