Beautiful mini Horse

I have a beautiful paint 7 yr old gelding. He's been ground driven and has had a saddle on him but as far as I know hasn't been ridden. He needs his own pen as he's determined to be boss, I bought him to drive with my other mini but it's not working out as I don't have the room to have him in a separate pen, he's very good with kids and treat motivated, 34 inches tall, asking 800 for him but open to reasonable offers
