He makes promises to advance your web site, or design an ad. The work is never produced, or it is not what you really wanted. He is great at BS, but you will not see the finished product.
He always gives some reason he needs payment in advance: "I can get you a special price if you act immediately...". He also gives you a time when the work will be completed, but you will never hear from him. Then, when you finally let him know that you are out of patience, he'll send you a note talking as if nothing is wrong!
Just save yourself a lot of misery - DON'T deal with him. It is ALL LIES! He stung us for about $4000 before we stopped paying him. Others have been stung much worse, but it can't continue.
