I assume you are familiar with the Kiev Survival Site ?.
Seems like the ribbons have broke, unusual for both to break. They must have both broken for the lower blind to be totally left behind, usually the lower blind is skewed as one ribbon still will pull the blind up. If the catch on the upper blind does not "hook" then there is a gap as the shutter is wound.
Cheaper to dump the camera and get another than pay someone to fix it.
The alternative is to proceed down the path to insanity and learn to fix it yourself, you will get much help here .
