A Murial painting on a wall

I am looking for an experienced artist to create a customized mural painting for the establishment of a new business in Melbourne Australia. The wall measures 100-500 square feet in size, and I am looking for a graffiti-style design. This project will be an integral part of making a great first impression on my customers, so I'm looking for someone with the talent and skill to create a one-of-a-kind piece of art. I am looking forward to seeing the ideas and creations you come up with!
