The car is very fixable with only a slight chance of the B pillar being bent ( the one between the front and rear doors ) This is a 1 or 2 day job with replacement doors. The most work will be repainting.

A few things, don't try to open the rear door, the dent looks like it is pressed into the glass and the change in stress might break the glass. I'd also tape up the inside of the rear door glass in case the glass does break. Yes, you might lose the tint but this is far better than cleaning broken glass. At minimum some cardboard taped on the edges would contain any broken glass. Also keep it out of the sun, thermal changes can cause stressed glass to break.

Have a look on car-part.com This searches participating salvage yards. Call the yard directly as many have not figured out e mail.

When you do fix the car , be sure to have the existing doors rough pulled before removal, this way metal you are keeping gets bent back into shape.
