If you mean campaign manager, I guess the salary is 0.01 per week or 1% from the total payment of signature campaign per period.

These days it only cost you 19 BTC per week. But you have to be very active. A min. of 60 minutes to an hour per weekhour.
If you can do that, potentially you can become a very wealthy man, if you've got 60 minutes to an hour per weekhour of free time.
