T-way can make that for you, he does good work, like 1petrofan mentions.

Make sure they use transparent white vinyl and either double strike the black (printing) or place black vinyl on it. Give them the Image above and a few dimensions and you should be good. Should cost around $50-$75. To save a few dollars, go to "vector magic" website, upload the image, and create your own vector image of it. That'll save on artwork charges.
