This sounds like a very interesting project that I would like to work on, but unfortunately the payment is not guaranteed. Making the payment guaranteed will draw higher quality designers giving you a better chance at receiving more quality submissions. If you decide to guarantee the payment please let me know.

In looking at the brief I've already got a couple general designs that come to mind. Please let me know because I have a few questions before starting on a design.

A huge difference from the initial brief!
