I had been encouraged to try 99designs, and as the need was urgent, I did. The initial minutes showed an immediate response, and what a response. There was such a variety of designs, responses to feedback, approaches from a different direction, such that I was torn between excellent answers to my question. I never realised there could be such competition. I have already begun another competition, and I will be using 99designs again, and - I think - using them often. This has completely convinced me of the value of the site.
