Do I Need A Choreographer?

I already know how to do different syles of dances and the ones that I dont know how to do my parents can teach me so is it really necissary for me to have a choreographer? At first I thought that it was necissarry but I`m paying for half of my court girls dresses because the cant afford it. If I have to have one then could someone tell me where there is an affordable choreographer in South Florida (Broward hopefully)?
