This is the opposite of what investors want -- one of the reasons I'm a serial bootstrapper. Your attitude will either repel VCs, or they'll invest anyway and force you to make short-term decisions to maximize revenue.

I don't think the VC route would be easy for you, nor would it make you happy. Good for you! Look for info on how to bootstrap instead.
