I've found out the rate that at least a couple of the clients would pay to get my time, and I find it expensive. I don't find it surprising that one person I talked to, said that they have specifically requested that no one based in the UK for forwarded to them, because they would be, almost by definition cost more than they would be willing to pay.

And yes, I have been told by several clients that I would be an expensive hire. And then I don't get hired, in spite of what is usually a highly productive conversation/interview.
