My camera got wet and a white film appeared inside the lens that makes photos very blurry. I don't want to take it apart and most likely mess the camera up. Can you fix that and if yes, how much would it cost?

That's most likely moisture inside. If it is over 5 years old, chances are that repairs will cost as much if not more than that of a new camera. You'll need to take it in to get a correct estimate. They can't give any information online. Not even ballpark figure

Yes, they can fix it. Depending on the camera model and extent of the repair needed will determine the cost and if it's worthwhile to fix it.
