Muna - there are so many different ways to recruit participants for qualitative interviews: The list below contains some of the more common ones - and they can be used alone or in combination with each other:
Posting Flyers in places where your potential participants are most likely to gather.
Approaching companies/professional organisations to ask if you can present at meetings/forums.
Approaching the same companies/professional organisations to ask if you can post details on their main web sites/site forums.
Doing similar within your own institution.
Using social media i.e. Facebook.
Consider using 'snowball sampling' if the participant group are hard to reach.
The main thing to consider here is that you need a pre-planned proposal for which techniques you are going to use - and ethical approval to use and conduct them. The attached chapter on qualitative sampling may further assist.
Muna - Make sure to choose only those participants for qualitative study whom you have access and have experience with the phenomenon under study and are willing to speak about their experiences and thoughts. participants who are willing to speak about their experiences. The first step you should take is to identify and describe the type of participant you need. Sitting and taking time to brainstorm and write out a description of your ideal participant. Second, build a research panel and create a database of potential research candidates. Third, use social media channels and ask participants for referrals. Further, Dean Whitehead has provided a detailed answer and follow it.
I totally agree with Dr Manzoor Hussain and Dean Whitehead but here is something I would like to add here. Actually, this is what we did for our MBL case study.
Every university has some sort of media house, they have cameras and staff to operate them, including experienced focal person. All you have to do is; craft your research questions and voila!
Next week you should go back to your university and discuss this leverage with your program manager. And do update me with what you find out :)
