HS Marching band hoodies - where to order from?

Hi! I'm a senior in my marching band and it's been tradition where the seniors design a hoodie according to the show for all marching kids to order. It's not mandatory to order and we all get t-shirts that the staff design at the beginning of the year. I'm based in Indiana and I'm just looking for good companies to order from where it won't break the bank for high school kids. We want to try to have multiple colors (for the design) on the hoodie, our theme is flower based, BUT we are open to single color for the design (white). Any suggestions?
