I'm looking for a service to collect feedback on mock-ups (screenshots) from my internal team and a private set of individuals selected by our team. I want to host the mock-ups and have some survey questions and a comments field. I want to be able to have different options for the same page and have them displayed together on the same page. Is there a service that offers this functionality?
Your requirements are a little beyond the scope of this site, but I generally post to conceptfeedback.com when I'm looking for design related critiques and (if lucky) UX feedback.<p>They also have premium options for more 'hands on' feedback. Sounds like what you are looking for requires a little investment anyway.
