My company is starting an equipment rental service for emergency operations and is considering various types of equipment for rental. Handwashing stations are on our list of considerations.
Please include shipping information for these units up to a full 20' container quantity. Our initial consideration is for 50 units although a 20' container quantity if discounted from a smaller quantity will be considered.
