You cannot answer that question that simple. I think it mainly depends on the annual work load. If you can prove, that the business can be run with 1 hour per day, they will accept a director's fee of about 8k. But that simply depends on what he is actually doing. As we do not know, we cannot answer. I personally would abstain from such non sense in the EUSSR while living in your homecountry with citizenship, mother, kids and you whole childhood, it just smells too much.
