RC Marine Vehicle Design, Semi-Submersible Deployment Platform

Looking for a designer to assist in the development of a RC marine vehicle used to deliver payloads through the ocean surf. Unit will be semi submersible operating via remote control from within 2 miles.

Unit Requirements:
Commercially available motors, controllers, autopilot hardware, radio systems, gps equipment, and software are a must.

Sealed and waterproof electronic sections.

Quick battery swap capability

Will need a operating radius of 2 miles.

Fail safes and reliability in hazardous conditions.

Navigation lights to ensure direction of travel.

Two servo controlled actuators to release payload.

Extra: Unit should be able to be upgraded with video capabilities and a minor sonar for depth/ drop off ranges.

Operation: Unit will be deployed from surf and drive out to designated waypoint. Once at waypoint a button on controller will be pressed and release servo will be actuated and payload will be released. Once payload is delivered to required waypoint, device will return to launch.

Starting point: Rough drawings, ideas and load requirement. Everything else is an open concept and look forward to working with a brilliant mind to put my concept into action. There are other similar devices on the market but none using semi submersible capabilities to overcome surf.

Thank you all in advance!
