For $1800 they better be working my horse every day of that 30 days, and I better get a totally finished horse back!! Not to mention massages & chiro for the horse, a cushy stall, fresh bedding daily, the best food...the works of a five star horsey hotel! :) :)
Honestly, I don't think I would ever pay that...even if board is included.
I think in our area, the average of board + training for 30 days is about $750 (board being between 400 and 500).
