Average PL wage is about 60k per week isn’t it? That surely sets the floor if you’re wanting to keep him.
The median wage (i.e. so it is not distorted by anyone on the GDP of a small country a week) is probably a bit lower, but I believe you're right on the mean. You could try that, but I'd have no problems going up to 80-100k a week. It sounds a lot on paper but 4-5 million for a year of Iliman is not a gamble in my eyes
