Are you based in/near London?
I am and I would be interested in taking part in what you're proposing, so if you are doing something near London please do announce it on these boards.
Myself I have a tiny business (nothing compared to the turnovers you mentioned earlier) that does accept bitcoin payments, but doesn't sell anything related to bitcoin so I haven't run into those issues. I do buy and sell bitcoins personally and have had a number of negative experiences with banks. I also have seen this a lot on these boards. I'm interested in the adoption of bitcoin the UK and feel it is a shame the way things are, would be interested in doing something about it.
Hi Griffers,
Firstly apologies for the lateness in reply - it's my birthday (hint, hint) so been a little sidetracked

.
I am not actually based in London - I live in Liverpool but am from around Bristol (still spend a lot of time down there). I will email the relevant people tomorrow and will keep everybody posted on what has been said. If all goes well I am sure this will involve something going on in London as its the most logical place to begin.
I can't thank you enough for showing your support - we can do this

James
P.s. Again - I WILL keep you posted
