Paying employees by the hour is basically writing a blank check...

Agreed with Miked. There come a point(which seems you may be at) where(from what I have heard) you have to change gears, yourself. Go from being overseer of all to delegating tasks, slicing up the responsibility pie...

It sounds like you are just at a difficult point, I hope someday to have those worries as it smells like a recipe for success may be cooking.

Now I'm hungry, perhaps overindulging in the food/cooking metaphors is my stomach overtaking my brain.
