Survey help: Set up an online Matrix form and collate results

Hi,

I need to conduct a survey assessing member benefits and values. It will be in a matrix form and people have to fill in which members they believe value which benefits. I need to do this via some kind of form that people can easily fill in online and then I can collate the results. I plan to survey around 30-40 people.
I've attached the spreadsheet of the matrix I want people to fill in. They just need to put an x in the box if they think that type of member appreciates that benefit. I would also like one comments box for people to add more information.
Ideally this would be something they submit and I can easily see the results. The aim is to look for patterns of which benefits can be grouped together.
Can anyone help with this? Please explain in your proposal what you will use to do this.
Thanks
Rebecca
