I assume the manager would need to charge something similar (hourly rate) to what you charge even though you may be doing the more highly skilled work. Pay based on skill might be more important for more traditional employment scenarios as opposed to freelancing because of the nature of freelancing (making a living from relatively uncertain circumstances.) A manager may even have to charge more (percentage) assuming the number of hours going into the management comes out to be far less that of the coding. Perhaps the best way to do this, especially if you would need to meet with this person, would be to make some sort of arrangement with a local dev shop which does client work.
