Try it yourself and save some money. Get the pressure treated wood at Lowes and get precut carpet at the local boat dealer and get some stainless staples. Prepare the new bunks with carpet, holes and hardware at the house, take the boat to the lake and once you unload it go back to the parking lot and change the bunks. Should be pretty quick. My buddy did his that way and i did the same. Actually my boat is so light i used a floor jack in the garage on mine. Good luck.
