I'll point out the obvious - with such a low post count in all the years you've been here, I'll wager no one will want to help you out in the manner in which you've indicated. In effect we don't know you.
Are you a member on another board and can you give references? That would help. Then again, folks that come here without cred usually get short shrift. Not trying to be snotty, but that's how it usually is on all boards.
Your best bet is to find a friend travelling to the UK who would be willing to bring some back for you. Or just go yourself.
Cheers,
RR
