I would very much like to do vaulting (gymnastics on a horse) but how much would it cost?

i have done gymnastics and rode horses all my life, but i really want to try vaulting. it sounds expensive though. would anyone know where i could go to take it and how much it would be? PLZZ AND THANK U!!|||type in "vaulting stables around (enter city)" in google and that should get some places around wherever you live!
