Thanks for your responses. In answer to some questions, it is not a wind-up, however I don't have high hopes of meeting my customer's needs because, as mentioned, I know nothing about this type of machine. 'What traffic' hit the nail on the head really, as stated, I sell R22s, R44s and Enstroms, not 'busses'. I didn't put my company name as I know people are sensitive about advertising but if you are interested, the company is called 'helimove' and I am sure you are all familiar with Google!
It is a civilian heli that I am after but I have no idea if a suiatable helicopter is available, maybe it is the lack of choice that makes it seem un-feasible. Any suggestions are still welcome, thanks for your help so far.
