It's like this, they may not want to pay for doing it the right way, and you may not have the eloquence or the evidence to convince them, but in the end it comes down to this: Do not allow them to put your name on something like this. If you do the work this way, regardless that they "made" you, it's still your name attached to a piece of bad work. Sometimes that serves to convince them even when nothing else will. Often a contractor (for any kind of work, lik siding your house or a plumber etc...) when confronted with a customer who insists on doing something the wrong way, the contractor will say "OK I'll do it but only if you sign this waiver absolving me of responsibility so that when it falls apart I'm not responsible." In effect, "I'll do it but I will not warranty it even slightly." Faced with that, even cheap people sometimes get scared into doing it the right way or at least doing nothing until they can do it right later, or unfortunately finding another contractor with less scruples and/or skill sometimes. You can't say that since you're not an independant contractor, and in this case I wouldn't settle for that anyways. I simply would not allow my name to be attached to something I don't trust. And you should not trust this arrangement. Brian K.
