Multiple-Case Linkage System

Avg Bid (AUD)
Project Budget (AUD)
$250 - $750

Project Description:
I have 4 steel cases needing to be mounted to the bottom of a vehicle - wherever we can fit them. Each case has 2 knobs on one side. I'm looking for a 'DIRT CHEAP' way of linking the four boxes, so that from inside the vehicle we are able to turn certain combinations of these knobs. The force required to turn these knobs could be anything up to say 80psi.
Though I suspect that hydraulics is the way to go I'm thinking that the cost would be way too high for this application, or am I incorrect and it can be done 'DIRT CHEAP'? What other options are there?
I need someone to design a simple linkage system and how it operates from within the vehicle..
