Survey Employee Satisfaction

This is my first ever post and I have no doubt put it in the incorrect place hence apologies in advance Steve :-)

Anyhow, I'm quite a HR novice (Studying Level 6) and would really appreciate some help please.    I am currently assisting management within our company to bring our very disjointed team together.  As a starting point, I have been tasked with asking all employees to complete an annonymous employee satisfaction survey (preferably on line with collated instant results) ....can anyone please point me in the right direction as I can't see if such thing exists or am I asking the impossible?  I did a google but no joy.
