Thanks for the replies so far.
I must have missed the 'Skyviews' ad.... it has nothing to do with them, but you and African Drunk hit the mail on the head. The thing I would fear most is being pressured in to a situation that could land me in hot water with the CAA. I'd like to think that as aircraft commander I'd put my foot down and say 'no' if I were asked to do anything dodgy...... but having no commercial experience it is a worry.
Anyway, this outfit may well be perfectly respectable. I need to do some more digging.

ps Timzsta, you sent me a PM but I can't reply as your mailbox is full.
