I just moved into a newly constructed home and had to pay to have the same fence as you describe returned to the house on both sides. I think we ended up with about 8' one post on one side and 3'*2, two posts, plus 4' gate on the other side. It came to about $815. I think your quote sounds about right. Also don't forget to call and update your homeowner's insurance. It should go down, which is nice.
