Audience Research

I am now creating my audience research questionnaire.
I am including questions such as:

• Which name for a Classic Rock magazine do you prefer?
• Examples of Dominant Image camera shots
• What tone should the image be in? (colour or black and white?)
• How much would you pay for a MONTHLY magazine?
• What colour scheme do you prefer?
• What article would you be most likely to read?

I am going to ask at least 10 people to answer my questionnaire.
