Ask HN: Does my homepage need a "How It Works" video?

We just launched our site and we are constantly conducting user testing. I was hoping to get some feedback from the HN community. Does our homepage simplify what we do? Do you understand immediately what we do? Do you think a "How It Works" video is required? We are about to test all of these things but I prefer to hear from HN first to better frame our testing. The URL is http://www.Jobzey.com I really appreciate any feedback you guys can provide.
