Thank you for clarifying the situation. Pressure from family without commitment from you will be futile. As a part-time student, it will take nearly 5 years to complete your research and submissions. Can you spare time?
SERVQUAL Model
Kindly see the SERVQUAL Model - Express Healthcare and see if that interests you and if your organization can provide you with the facility to conduct primary research. You can find more info on SERVQUAL on Google.
Also, see

So, you see, finding articles is easy. I just did a Google search. I have applied SERVQUAL to teaching, and my papers (Narasimhan, K. (1997) and (2000)) have been cited by quite a few.
