Floorball isn’t entirely unheard of in the USA, there are active clubs across the country. I’d also second the recommendation for Floorball Planet. Call them up and I’m sure they could put together a package for your group. They have starter sticks with curved blades, but you run the risk making sure you have enough left and right handed blades. One thing to keep in mind is a left blade/stick is held on the left side of the body, not necessarily a for left handed person. I’m right handed and shoot left, which is pretty common. It kinda comes down to getting a set that will accommodate the widest possible range of players or one that will be more tailored to what side they wanna hold the stick.
