We are looking for a factory that can produce a cableway system like in the video links below, these cableways are made to pull a person around a lake so they can water ski most have 4 towers 1 in each corner and a cable that is strung around the 4 towers can attach and detach a skier at the control tower from the number 1 starting tower, please have a look at the video then give us price on 4 towers, motor to move the cable up to 30 miles per hour, and all the rigging to make the system work.
