you will always be better off modeling by hand. there is something in some cad software and simplify3d called a heightfield. this will take a photo and turn it into a flat 3d extrusion. i have used this to make lithophanes. im not sure though how it will work with that logo because its flat clipart with no shading or depth to it. you would really just have to try it and see. i doubt it will give you the look your going for though.
