removing quarter panels and doors

So everyone knows the the northeast gets pounded with snow, and last week i was driving on the highway and hit a patch of black ice and spun into a guardrail. it did significant damage to the right side of my poor cavy. as of right now the dents created from the guardrail are pinching into the front right door keeping it from opening more than 3-4 inches and the rear door won't open at all (were figuring its a jammed or busted locking mechanism). I'm currently a college student with big loans and few dollars in the bank account, I can't really afford to go have a garage look at it or fix it.

I was wondering if there is any way to remove the front right quarter panel or a good way to at least bend some of it back so I can get the door to open

thanks,
Doug
