Dear Mawathage,

I would suggest you have four viable options:

Perhaps a combination of several approaches would be appropriate?

If by qualitative survey you mean a series of qualitative interviews, then I would recommend the book by Rubin & Rubin, Qualitative Interviewing: The Art of hearing Data.

Dear Mawathage

You may use following methods

Case study

Interview

Focus group discussion

Telephonic interviews

Dear Mawathage,

It really depends on the purpose and dimensions you want to tap in your Project.

Since you will be doing a qualitative survey, I would tend to opt between:

Semi-structured interviews

Focus Group

Snowball Method

Or, as it as been said, a combination between quantitative and qualitative approach.

However, it really depends on what you want to know. Answering to that question will make clear the adequate method to use.

there are lots of qualitative methods, probably there is no "best" method but depend on the availability and so on. a thorough explaination of qualitative methods could be found on SAGE HAND BOOK - Qualitative methods, there are lots of varieties of Qual and you may read through and talk to people who are experienced in your research area about the practicality and the availability about them, talk to your supervisors are also a good way to find out more. 

All the best!

A survey is more positivist and qualitative research is based in interpretation. Survey also refers to an overview, which is more concerned about breadth. But qualitative research is more concerned about depth. So I find survey and qualitative as two contrasting terms. 

Dear Mawathage,

I would suggest you have following viable options:
