One of the clients I've been contracting too has presented a difficult problem. I've created several different composites and mock ups of a new UI for a webbased application. However, they've veto'd everything I come up with. I feel like they have a very specific idea of what they want, and they just aren't clueing me into it. They've also unintentionally withheld (just didn't think to give it to me) alot of documentation on the app (which would have REALLY helped in the first two weeks of my work, when I was still struggling to make sense of the whole shebang. Is it time to let this client go?
