Here is my example that I may use for a new freelance client's program about a service that cuts the time it takes to get people into a new home. 

Need a New Home Now? We Can Make It Happen

I like the pairing of illiteration with the class tip of using a question. I think it helps get the idea stuck in a potential buyer's head. Then, hopefully, the second half of the headline is enough to get them wondering, "hmm... how can they help me get a new home, stat?" A lot of this plays on exigence and speed, so I'm hoping "Now" is strong and urgent enough, yet still short and sharp.
