Really fancy, hmm... They strike me as being not very useful if they aren't willing to touch the code unless it meets some quality standard. I can understand turning down a contract if the code is total mess and the client wants major work done in an unrealistic amount of time or for too little money. In this case, why not reply more like "We're going to have to do some refactoring before we do X. If your budget allows for that, then we'll take the job."
