Audience Research (Online Focus Group)

Instead of using sites like Surveymonkey and Questionpro I thought it will be a great idea to create an online focus group of friends asking them questions about my questionnaire perhaps on email or through text message, I have decided to host my focus group on the IM messaging app Whatsapp.
I will have two separate focus groups which consist of separate people I will ask them the same questions and then collect their responses, I believe that the focus group can really aided me through my research because I can sample the responses of my audience through different stimuli and questions.

The response I aim to get from my focus groups.
I aim to get a variety of different responses from different types of teenagers, some of them may not even listen to Alternative rap, but I want to get their opinions of the processes that I need to make in order to make a successful magazine that my audience would find appealing, I would also like to here about their spending habits and how much they are willing to spend on a high quality magazine and a low quality magazine, as well as the content they may want to see featured in a teen magazine.
