Writing for Battery Percussion

I want to gain experience with writing for a drumline, so if anyone has a Marching Band/Drum Corps arrangement that needs battery parts, I will happily help! I march in my high school’s battery on snare during field band, indoor, and parades. I am also marching White Sabers in the coming summer. Any replied will be greatly appreciated! The software I use is Flat, and I will of course send Mp3s and sheets of the finished product. Thank you!
