You are mixing apples with oranges. First, I am not saying a client doesn't agree with my opinion. I am saying many clients believe a DJ simply plays music - nothing else. That is ABSOLUTELY an uninformed client. I have educated clients to the contrary MANY times. They come in thinking that, and they end up booking.The fact that a given client does not agree with your opinion of what constitutes "qualified" to do a wedding does not make them "uninformed."
This is not an advertising or communication problem. "Educating" someone on your point of view will not change their core values.
I'm in the market for a new vehicle. I'm goig to buy used because I am not going to spend more than $25,000 for a vehicle. That doesn't make me a "price shopper." I am not looking for the lowest price - I am looking for the best car under $25,000.
Buying a car is a bad example as that is a product not a service and people shop for cars several times throughout their lives.
