Do I need an instructor, a trainer or a coach?

In the equestrian world there are many people offering lessons, some describe themselves as instructors, others as trainers and some as coaches. But how do you decide who is right for you? And does what someone calls themselves really matter?
If we took a straw poll of the industry we’d likely get the following general definitions:
Instructor - Someone who focuses predominantly on the rider and developing their riding skills and technique by passing on facts and knowledge. Often has British Horse Society (BHS) or Association of British Riding Schools (ABRS) qualifications and will often work in a riding school, college or Pony Club setting. May have a more “do as I say” rather than a collaborative approach which is great when you are starting out and need clear and concise instructions
Trainer - Someone who focuses predominantly on the horse perhaps using their own system for producing horses. Often perceived as having ‘hands on’ experience through competing / producing horses for sale. May have a more ‘guided practice’ approach – this is what I do in this situation / this is how I train my horses.
Coach - Someone who focuses predominantly on competition riders / teams and preparing them to win. Often have competed at the highest level themselves and are now sharing their insight into what it takes to be the best. May have a more ‘eyes on the ground’ approach providing feedback on the performance of both horse and rider and how that relates to competition success.
