redesign an ultrasonic depainting line

I am looking to redesign an ultrasonic depainting line with a current capacity of less than 100 parts per hour. The main problem with the current design is its durability, so I am wishing to change the overall design in order to improve the line's longevity. I am seeking an experienced freelancer who can help recreate the current depainting line with improved durability and long-term functionality.
