I feel like I'm going to be around the top price, but I think it might be interested to know what it could cost.
Tack: $2500 (English saddle [hard fit, I had to get a Butet], stirrups, stirrup leathers, martingale, bell boots [turn-out and riding, had to be neoprene free because of an allergy], and jumping boots [again neoprene free])
Board: $650 per month +$25 for a heated bucket or a fan during some months
Blankets: $1200 for two sets of blankets (2 lights, 1 medium, 1 heavy) I show and clip in the winter so blankets are needed
Shoes: $100 (my horse has four shoes)
