I earn more for the company doing other tasks in that time than the $12 it cost to have someone else do it, there are only so many hours in a day, I would rather spend them producing profitable, enjoyable work, rather than figuring out what generic sans serif font was used in a logo.
Yep - I happen to have the skill set, and it's very convenient for my boss, because I'm good, and quick. but I'm more valuable to him with production work. my time is more valuable running the machines - producing. because I'm good, and quick, he just wraps the design part into the cost, or not, depending on the customer, and the complexity of what needs to be done. He'll state the design fee upfront with a new customer. If they really need our help/services, they will pay. but we offer design to a point. Like Canuck said - I'm more valuable making stuff, not designing it.
That said, we have some large customers who are regulars, and they keep coming to us for the quality work, and because I've been building their artwork for years. I know what they need, and come through every time, and it doesn't take me long, because of my background. they don't care what it costs, they know they are getting quality.
I know, I know, you all wish you had me on staff. too bad, I'm spoken for
