The 99designs service is incredible! I paid about the same amount I would pay to one designer with one set of ideas and I got 348 submissions from 47 designers and ended up with an amazing new logo for my business. The ability to interface with the designer and give feedback makes the process fun and allows you to get many iterations of the designs in a very short period of time. I would wake up each morning during my contest excited to get on the computer and see the new design options! I would use the service again and again for my design needs and would highly recommend it to others.
