I would guess 186K miles per second if I'm at rest relative to the point of emission, though probably not if I'm moving away at 93K miles per second relative to it.
Regardless of your movement the speed of the light beam remains the same. You are attempting to indicate that the speed of the light beam is relative to your motion and that is incorrect.
As an example. You are driving down a long highway at a constant 60 mph, eventually you pass several cars. One is stopped by the side of the road, one is doing 30 mph and one is doing 45 mph. As you pass each car you look at your speedometer and you are continuing to move at a constant 60 mph. Your speed has not changed and is not relative to the speed or lack of speed of the other vehicles.
