Carpenter Job in Broken Arrow, Oklahoma

We recently moved into a new house and the old owner left the hot tub. It is a Cal Spas Genesis Smart 2-person (can seat up to 4) model. There is no water in the hot tub right now. It is housed in a shed, so it has not been out in the elements. The owner said it works great, but he had not used it for about 2 years. It is clean. I'd like to trade this for labor on a new stair case banister with metal decorative spindles. We are located in Broken Arrow, OK.
