My first legal letter

So I am trying to get the security deposit back from the last house that Jessi and I rented. The landlord puts on the front of being a pretty good dude. But after nearly a year of living in his house I know that he is a scumbag landlord. He made a lot of promises during our tenure. The longest lasting B.S. came with an engine (yes, like out of a car) in our driveway the entire time that we were in that house. I didn't keep track of the number of times that I asked him to move that damn thing out of the driveway. And inevitably he would tell me that someone was coming by and they would be there in the next couple of days. I listened to this speech probably 15 times before I stopped bringing it up. We never got a copy of our lease. We never were able to do an inspection, either at the beginning or end of the lease. He took some of our screens "to fix them" and never returned them, despite multiple phone calls asking about them. And as the final little gem of joy, he is trying to keep our security deposit to replace carpet in the whole house even though it was old and disgusting when we moved in. I will agree that one of the rooms carpet was completely ruined. But that doesn't mean that we should pay for the whole house. And I doubt he really replaced it any way. Regardless, I wrote up a legal letter with a little help from the Legal office at my work. I was going to attach it here, but I can't figure out if that is do-able. So instead, I just wrote about it. There you go!
