Thanks for the input guys, after some detailed discussion of the expectations the price magically rose (funny how that happens). I don't feel it was them trying to scam or anything, just that the original figures were not given by the appropriate person. Once the actual estimate was formed with their magical software as though it were an insurance claim, the price almost doubled. No hard feelings, but for that price its back to me just doing the job myself. Probably just going to limp it through another summer and deal with it next winter....
