I need to paint my house. the problem is that the house over hangs a "hill". From the bottom of the hill to the peak is over 40 Ft. I have seen a device that has two posts that run from the ground to the soffits. Between the two posts is a ladder type platform. You step on a lever and the platform ratchets up the posts. What I need to know is the manufacturer of this type of contraption. I was quoted between 8 and 12 thousand to have someone paint it for me.
