I'm in North Texas... where do you board? You should move your horse because that guy sounds lazy. FYI most boarders provide their own blankets and I wouldn't share blankets either cause you horse could get fungus from another horse.
I charge $275 (cause we are still doing some construction on the arena and roundpen) but I take care of my boarder's a little too good. I don't know what kind of facilities your at and if it's worth puting up with his behavior..
My website is www.geocities.com/jolicheval if you click on services and then boarding you can get an idea of what we provide for comparison.
Also the place I was looking at boarding at was called Mystic Acres. Not sure if you have heard of it. Also I checked out your site and you have a nice place.
