Holy crescent wrench Batman! We just got a proposal (i.e. bid) from a plumber on our very small not opulent cottage like cabin. There must be some kind of mistake! We immediately are looking into ways to cut costs on this one, perhaps just use a plumber to rough plumb things in.. who knows! We are scrambling to get this organized and much much cheaper! I think I will become a plumber in my next job incarnation... however, I don't want to crawl under houses because of the spiders that may be waiting there for me....so I may be out of luck.
