There are a surprisingly large number of logo and design contests to be found online. If you are good with image creation using digital or traditional tools, then you will want to keep an eye out for these contests. Each contest is not just a chance to make money – some of the prizes can get quite large – but also to get your name out and in the spotlight.
As with all the highly-creative methods to make money, you will need a goodly bit of imagination and aesthetic sense to pull this off, not to mention the actual technical skills. Many logo contests are held by companies looking to modernize their look, and that means you will need to get a good grasp of the contemporary art styles.
Unlike in graphic design, logo and design contests will constrain you with rules and requirements. However, you can also view these not as restraints but as guideposts to help you direct your energies more efficiently.
Remember that your art will face much analysis and criticism, but if you do win, then it was well worth it. You will need to bring your A-game every time, should you choose to pursue this path.
Remember to review the rules and regulations of the contests, specifically with regards to the Intellectual Property rights after submission.
