Can you help me design a Tattoo?

I am attempting to design a tatoo for myself and I need some help coming up with something legit. I am getting it on my back left shoulder as a reminder of the 3 lives (potentially more) that I have saved over the years as a lifeguard. I was hoping to do something involving the fact that they were saves I preformed as a lifeguard and the roman numeral for 3 (or whatever the final count may be). But again, I'm having trouble coming up with cool designs. If you have ideas or could possibly draw and post something that would be great. Thank you all!
