Art Designs

I am looking for 7-10 new designs for my charity items. The main item will be stickers (the oval type (6 inches wide by 4.25 inches high) that are seen on many cars). The same designs however will go on other items such as tshirts, hats, etc. The designs are for survivors of various diseases and traumatic situations(cancer, leukemia, abuse, rape, etc.) The design focus shoud be a capital S. The capital S will be the most important part (when someone sees the S they will know that the person is a survivor). Somehow the design needs to incorporate what they are a survivor of. For example, the color pink is used in the awareness of breast cancer. A pink S on a dark background, or a black S on a pink background could be used. A pink ribbon can be incorporated. This is where I lack the creativy and need some help. Artwork needs to be delivered in high quality digital format.
