I suspect, even at £180/hour, she will be VERY busy
I think you're right Grumpy, as much as I'd rather not pay £180/hr, I probably will, and I certainly won't be the only one.
Mil makes a good point too, It's very much about supply and demand, and if she can get away with charging that why wouldn't she? When I saw her last time round she seemed very switched on and business-aware, and I would expect that she's researched the current state of the market and priced her services accordingly.
What we really need to do is all get together and agree that no-one goes to see her until she drops her rates
Of course we are a fairly small part of the potential customer base so that probably wouldn't work
