Hi Matthew,
I don't know if they would be willing to offer any free advice, but this is the same service type and training that is being given to firebrigade personnel.
Most of it is how you shouldn't do it, stay out of the water type message. But due to what your doing they may be able to provide some good quality information.
They are an American based organisation but recognised as world leaders in there feild.
This is one of there UK bases, I know there's one in Northants but can't find the relevant information.
Good luck.
