Thanks for your comments so far.

I have already contacted Airwork and they don't have a suitable machine on floats available at the moment, although they did say that they could fit floats to one of their machines purely for the endorsement, but I'm trying to avoid that expense if possible.

Will try Chopperline although I don't think they have access to a B47 on floats either.

Thanks for the advice but I'm looking at a fixed float operation.

Thanks mate. I will check these other guys out.
Any further assistance would be much appreciated.
