Average cost to fix 93 Plymouth Voyager door hinges?

So it's really freakin windy here and a few days ago the wind about ripped my arm out of its socket, and swung the front penger door of our van way open. Now the darn thing won't close properly and I think I'm gonna need to take it in. Does anyone know a basic, average price to repair this? I think the hinges just need to be re-aligned. Please help!
