2004 Chevy Cavalier dent in passenger side door

There is a big dent on the passenger side door of car. Im not sure exactly when or where this happened. Some time in the last 4 days or so in some parking lot. I rarely go to that side so I never noticed until today. The door won't open all the way and is unusable. There is also a plastic sheet that goes over the right front tire that is bent down. Anyone have a ballpark figure of the repair costs for this? I just want some idea before I take it in for an estimate
