There is no substitute for quality, and, for the most part, quality is recognized and appreciated. In a surgeon, no one wants a renaissance man. The last
thing you want to hear is, "Yeah, I guess I can do that." Clearly, that would indicate that this doctor was not concerned with quality. He isn't worried about how well he can execute this unfamiliar procedure, he just knows that he knows enough to not take your life in the process. Same goes for any type of handyman. You don't want your plumbing team to look at each other with a shoulder shrug and reply "I guess we can."
What you want is a specialist. You want someone who does one or two things really, really well. Ideally, you want a person who has dedicated their life to making sure they can do one thing with the utmost skill and care.
We do two things: K-12 websites, and local government websites, and we do those two things really well. We are often asked to provide alternative services with the resources we have, but we politely decline. At ezTask, we would rather provide you with an outstanding one or two things than with a mediocre range of products and services. After all, we respect renaissance men; however we would rather have electricians wire our light fixtures. But that's just us.
