CNC Vector Design for 3D Print

I need a vector design for a CNC 3D printable picture. This design should be suitable for 3D carving using wood and designed to be part of a frame with a design of approximately 4" by 20" wide. Could be longer but have long desired to make a pin board for gaming with a true "Wall of Shame" engraved design. The ideal candidate should have experience with creating 3D printable vector designs and be familiar with the intricacies of CNC machining. A portfolio demonstrating previous work of a similar nature would be highly beneficial. Please ensure the design is not overly complex, but still visually appealing when printed.
