I wouldn't really trust someone who taks like that to a client to give good results. Very unprofessional, he has no right to ne rude to you, ecspecially when he is giving you crap like those.

edit: also try looking around TFL, there are a few cheap banner makers that have really good results. I also may need a banner design to add to my portfolio so if you hit me up with some details I could probably make you one form free.
