-It is easy and free to distribute and collect surveys online.
-Zoomerang and SurveyMonkey are my favorites online surveying site.
-Both offer free basic surveys.
-Premium survey types and statistical analysis tools available for an extra fee.
-My only caution is that neither of these services are perceived as being "professional" and so they are not necessarily appropriate for distribution to customers or prospective clients.
-Of course, this is a matter of case by case judgment.
