Your Design Fix video call will last around 40 minutes but will depend on your challenge. It will be plenty of time to get expert help and leave with a clear plan. Your designer will then spend the rest of their time preparing your deliverables to fix your design dilemma.
The design fix will total three hours of designer time but not all of their time will be spent on the call with you.
