Amusing cartoon for home page of website

I need to lift my site and make it lighter and humorous. It is about helping people. Instead of the image I would like a cartoon. It needs to be dignified but could contain a joke. The cartoon will occupy the space of the current countryside image. I need an illustrator which can relate to the subject matter. Please read the site before replying
