Who can i contact if i believe the demon that has tortured my family has entered my daughter?

As far back as i can remember i have been haunted by something evil. each house i have moved to he has been there.my four daughters and i moved into our present home seven months ago, he has tormented each one of us but he seems drawn to my 14 year old daughter since we have been in this house.She has been physiclly touched by him and is tortured by him we have photgraphed him and he appears to be a man but with an undiscribable face.we moved in with a friend to get away from it after a failed blessing on our home. my daughter and a couple friends went to the house to get some clothes and all of them seen him in my childs room they left came to me and told me what happened.both my 14 year old and her friend went to to the friends home located directly across the street from our haunted home.they were there about 30 min when i recieved a call from them saying he was there with them at this friends home.they walk to were my other child and i were at when my 14 yearold walked in i could tell she was different.
