I am writing a funding proposal. I am finding it difficult to fit the following expense into a suitable category. Can I title it as 'Survey Expense'? (note that there are no specific categories, but of course, I have to mention one for any expense I make). However, I suspect that this may put off the funding committee because they may argue that why don't I just have the survey form filled for free using my students' help, etc.
My proposed research will involve taking surveys from several people. For this reason, I would use paid services from websites such as SurveyMonkey and other resources. I also plan to give some 10 odd gift vouchers of $25 to survey participants to encourage them to take the survey.
Any guidance will be appreciated
