I am part of a university research project that is considering ODK Collect as the data collection tool for our Android tablets. This survey would be around 25 questions, using the ACASI format (audio computer-assisted self-interviewing). In other words, we want sensitive questions' audio to be played by the app (with surveys in 4 separate languages). I have read that it's possible to do a code workaround so that questions play automatically instead of by pressing a button.
Here are my questions:
How complicated would building this type of survey be in ODK? Should I hire a programmer or can I do it with limited programming knowledge?
Roughly how long would this project take for a programmer to do?
Is ODK simple enough to hire a graduate student with some programming knowledge?
What is a reasonable pay rate for hiring someone to build this?
