I pay $350 for a co-op barn. That means I have to do turn out, supplements, vet/farrier/etc. scheduling, and mucking myself. That pays for hay, shavings, water, grain, 4 turn out pens, 2 arenas, (minuscule) trails, hot wash rack, trailer parking, hand grazing area, and a 12x12 stall with a 12x12 paddock. The feeders change, but we have no hired workers. I also own a paddock down the road for $200 that I use to keep hay in.
