Gearbox

Hi Guys
I have a vertical axis generator, it works at a speed of around 80 rpm, and I expect torque of 50Nm (I will use it in the water - speed=2m/s).
Do you guys have any idea of how much it costs a 1:5 or a 1:7 ratio gearbox? The wind generators usually work at around 400rpm.
Talking about speed, do you guys know the speed of this fisher paykel motor? I´ve got one here too.

Regards
