My field of study is business communication and I tried to gather responses for my survey by contacting target audience by email directly, however response rates were next to 0%. Now I'm considering using paid participation survey service to gather information I need (which is possible with some screening).
1) How to include "paid participation survey" explanation in my methodology section? (Should I mention paid participation at all?)
2) Is it normal/generally accepted to use paid surveys in Academia, because articles I read on my field never mentioned it?
