You’re making assumptions. I’ve worked with a lot of companies doing newsletters, websites, etc. In many cases your method would be wasted effort and frustrating to the client. They want someone to “just do it”. They don’t want choices, they don’t want detailed explanations of each choice. They want an “expert” to make the decisions for them and know that they’re the right ones. A “quality” marketer–for them–is one who steps up, makes the choices, and lets them work on their own business. They would see your way as “poor quality service”.
You’re falling into the trap of thinking that your way is the right way for everyone. You’re confusing “quality” with “best it can be”.
Let me give a real-world example. Razors.
For personal use, I “require” a razor that has a floating cartridge, an open back, a textured grip, a nice heft, and a reasonably-long life. That’s quality for me.
Tattoo shops and surgeries “require” a cheap, single-use razor that gets rid of most of the hair, and has a failure rate of 10% or less. That’s “quality” for them.
It’s giving plenty of value. It’s giving entertainment at a very low price. That’s valuable to lots of people (as shown by the fact that they bought the toys).
NB: “What the customer asks for” is not the same as “what the customer wants or needs”. Don’t confuse the two.
