That really comes down to you.
My time and energy is better spent on the creative, developmental, and administrative side. For me to spend the time to learn something I can farm out for a few bucks is really is a waste of resources. I could better spend my time making money versus worrying about trying to save a few pennies. It simply is not an effective use of time and my skills. When I used to do it myself, I would spend a week or a month on something a talented programmer could knock out in a few days.
In short, you need to know what your skill sets are, and how they are best used.
