Natural Beauty?

Hi there, Does anyone know of a school or anyone who might practice beauty and cosmetology naturally using hennas etc instead of chemicals? Am looking for someone to join our Holistic Day Spa in Bradenton Florida. There is a huge untapped market full of people that are sensitive to chemical usage and seek alternatives. But I dont know how to find someone interested in this not so mainstream practice of alternative health and beauty field. Any info would be greatly appreciated.
