How to prevent friend from posting on my Facebook timeline?

[joinme4coffee]

Is there a way to block a friend from posting on my Facebook timeline? I know I can block all my friends but I don't want to do that.The person in question is my daughter's best friend's dad and has been a family friend for at least 5 or 6 years. So unfriending is out of the question. He posts to my wall everyday, sometimes several times. Found out on his birthday that he had his wall blocked and no one can post to it. Why would someone block their wall but feel its ok to post to other people's wall? I have resorted to deleting his posts every morning from the day before.
I get to "Who can post to my Timeline' and the only options are 'Friends' & 'No One". There is no option for 'Custom'. What am I missing??
