Outdoor chalk artist -- 2

I am looking for a skilled outdoor chalk artist to create chalk art for a community event! The desired size of the chalk art should be 15 4X4 sidewalk blocks. I have some ideas in mind but am open to suggestions. The purpose of this chalk art is to promote a community event. The artist must have experience with outdoor chalk art and must be able to faithfully create the desired design. The ideal outcome is for the artist to capture the event's message while staying true to the original design.
