PixLab do offer quota based monthly plans for such task including standard face detection, shape extraction, gender, age and emotion pattern extraction. They do charge $0.9 per 1000 requests after you reach your monthly quota (1.1M API calls).

Not that much. Contact them and they will bring back with an offer adequate to your dataset and budget.
