Help required to build Freezing Tunnel

I am looking for someone who is interested in a bit of a "freelance" job. We are based in Argentina and I am finding it hard to locate a freezing tunnel at a price we can afford.

I need to contract someone who has knowledge on building continous freezing tunnels that can provide the plans, prepare a list of materials, do the necesarry calculations and be on stand-by for when we actually build it.

My plan is to contract persons in the frozen logistics business to actually build it for us.

Is this a possibility and anyone interested?, please reply.
