Hi, this is an interesting project you are undertaking.

In relation to sample size, this is a decision tthat you have to make.

However, sample size will depend on you methodological approach: what research design are you employing, what methods of data collection will be chosen? Etc.

For instance, a quantitative approach is permits large sample size as questionnaires can be sent to many people, however, if you opt for qualitative approach, you will be dealing with a smaller sample size. This depends if you apply focus groups or one to one interviews.

QUESTION to ask yourself re your Sample size: what is the study trying to achive? Will findings be generalisable?

I hope this helps?
