Landlord/Legal issue

Ive read also that suing for just the original amount gets you out of that clause. Which is why I was trying to get ahold of some lawyers but it was too late in the day at the time. I just want to get this settled. There was def wear and tear on that carpet as expected. I still want to talk to a lawyer who has worked these cases before to get a better headway on this. We havent filed suit but sent the letter out yesterday stating hes past the time to just send us a bill.
