Native Dutch person to check some dubbed films

I need a native Dutch person to spend a day sitting with our Editor . You will be watching three films ( 2.5 hrs long in total) and checking that they are correctly dubbed. You would need to come to our editor's office in Hammersmith to sit and watch these films. The only skill you need to bring is your ability to speak Dutch! We don't envisage this taking more than eight hours to complete. Our budget would be £100 for the day.
