Fiverr is terrible. You need to have really good luck to find a good designer. Once I tried it for a logo and they just stole an image with minimal modifications (adding text with a standard font), which one of my customers noted. I asked the original author of the image and he didn't know about it and gave no permission. Never again. Now I use always http://en.99designs.de . It's the best for custom logos, graphics and websites. More expensive, but original and you get multiple drafts from different professional artists.
