I don't offer anything like this at this time, but I have considered it. One thing that stops me from doing it is the potential liability. What if you get a contract to check and repair all problems and you miss something big that causes a fire or injury? Even if it was hidden, you could have potential liabilty just because you were suposed to find and correct the problems. I'm not saying you shouldn't do it, I'm just saying you should let an attorney draw up your contracts. Good Luck.
