Mitchell, I think the key here is that you are TRYING to get the customer to agree that you won't owe them any more than the inspection fee charged if you screw up. Most states won't allow this from what I have heard, so some contracts put in treble (sp?) damage clause (3 x the fee) to try and allow more compensation but still keep the damage limit within reason.
If you go to court and it is not a reasonable limit, your chances of having your limit and contract thrown out increase.
Any limit you can put in your contract would likely be more palatable than the judge or jury's amount if you screw up.
