Will you consider building out videos and demos for specific prospective users?

Not sure if you're a contractor for UT.com or not, but we don't use them for this purpose. Our clients are internal stakeholders. I honestly don't really care for their highlight reels anymore as I don't like that interface + they take too long to create. I just add the user clips right in my findings reports for that particular nugget.

The usertesting.com sales team is very informed and supportive. Im pretty sure if you contacted them directly. They will arrange a demo for you.
