Looking for artist(s) in search of a very public canvas

I own a house on the corner of Mendenhall and Friendly that sits high above the street, and therefore has a very long, tall concrete wall that is just DYING to be painted with something inspiring and thought-provoking. I'd love to talk with artists who have the supplies and the talent and want a very public canvas on which to express themselves. Email me at marcy@marcyray.net.
