I've had pretty good success with Facebook for these kind of user surveys, find a group or groups of the type of users you want to work with and check with the mods/rules that its ok to post surveys. I then use something like typeforms or involve.me to host my questions and make sure there are a few "qualifying" questions throughout the survey to later filter out responses that are a bad fit.
