Whether you use Fiverr or another design company, you should be mindful of where you get your logo.
If you pay somebody to design a logo for you, the intellectual property or copyright created does not automatically transfer over to you and your company. You must have it in writing that you own the copyright for that image, and that you alone are allowed to use the image in your business.
Unfortunately, most design companies use stock images. You never want to end up with a brand that's just a stock image. To avoid this, you have to be clear when you hire or engage the design company. Tell them to design an image or logo from scratch, just for you, and that they will not be able to license or sell it to your competitors.
