need help designing

I am looking to design 3 tats. one that stretches from shoulder to shoulder. without looking stretched or to big. i want it on the top part right below my neck . im thinking i want it to be a sun and then something in the middle of it to represent my battle and win against cancer. any ideas? Next i want some really cool tribal libra scales to put on my calf. i dont want that one centered i want it on the side and receding in. the third is on my arm and i want it to be some sort of tribal dragon in the shape of an s. i want it to start in the top corner of my pec and continue on to my arm wrap around the back and end right above my elbow. These all must be in black and white and if anyone has some ideas please contact me.
