Design/redesign/beautify a handheld remote control based on an existing Solidworks design in Solidwork -- 2

An existing design for an enclosure for a handheld remote control used in aircrafts should be redesigned or beautified. The original design is done by an engineer and not by an industrial designer. The design has standard push-buttons, leds and a roller button (for volume adjustments) and will be produced in plastic. The existing design is made in Solidworks and contains all circuits boards, batteries etc. The total project contains several modules (two remote controls) and two additional modules - but only the remote control described over should be priced. A reasonable amount of freedom will be given for the design. A NDA must be signed before the project is started.n
