Airboat variable pitch propeller system -- 2

We are only interested in talking to a freelancer that is an aeronautical engineer with propeller hub design experience. We would like the design to be mechanical and electrical (not hydraulic). It will use 12 V DC for the power. We would like the propellers to be able to provide reverse thrust in the design. The hub design needs to be enclosed because of the application being used on airboats. Airboats use a gearbox reduction unit that has an output shaft made of solid steel typically 2" diameter running at a maximum of 3000 RPMs. We envision a separate 12 V high torque motor with some type of worm gear that will push a disk that has bearings up against the propeller hub to change the pitch using a toggle switch to either put pitch in or take pitch out while rotating. This design must be very strong and the propellers that will be used will have a 1.5 "tube in the root and of the propeller to be used for fastening the propeller to the hub and pitch change. You do not have to use our ideas other than the propeller at the root and will have a tube to put whatever device you design inside of it to change the pitch.
