There are several online survey programs available in the web. My preferred software is Survey Gizmo because it has no limit to the number of questions you can ask and there is no limit to the number of respondents you can have (some online programs have a fixed limit for free accounts).
Although some of the features in Survey Gizmo are only available to those who subscribe to a basic account, the available features in a free account are enough to make a professional looking survey that is accessible and available to anyone.
What I like the most in Survey Gizmo is that it has tools that will allow you to test your survey as well as to simulate respondents through an online bot program.
