A 'Volunteer' to Equestrian Ventures would mostly only be doing the things described in the volunteer link, such as but not entirely limited to; checking fence, tidying-up, pruning, observation of training through relaxation/meditation methods with the horses, or maybe pasture poop pick-up or feed prep. A volunteer is not at all likely to be 'working' the horses. Grooming perhaps, if truly experienced already, but would not be training or playing with the horses on their own, regardless of experience level. Perhaps a volunteer would just be hanging out, in the relaxing environment, observing, with me as I am explaining my experiences with my horses. While there could be learning experiences occurring, I will not be ‘teaching’ a volunteer, per se.
A 'Working Student' at Equestrian Ventures, will be helping with barn/farm tasks, in exchange for - depending entirely on experience level - either lessons with me or working with the horses on their own.
A regular 'Student' or 'Lessee' at Equestrian Ventures, would be paying for - depending entirely on experience level - lesson time and/or paying for the time spent working on their own with the horses.

WHY DOES BEHAVIOR HAPPEN?
Generally speaking, we and our animals behave because, either there is something in it for us/them, or we/they want to avoid an icky consequence.
We/they are usually moving toward something desirable or away from something undesirable.
