Reliable and fearless leisure horse wanted

Reliable and fearless leisure horse wanted - I am looking for a lovely, reliable leisure horse between 6 and 10 years of age for relaxed rides on the beach, also on my own, which is also suitable for dressage work in the riding arena. As I am 1.78m tall, the horse should be around 1.70m. I wouldn't mind the gender or the color. It would also be great if it could stand alone in the paddock or at least be compatible. A barehoof horse would be good for my purposes. I can't pay a lot of money for it at the moment, but the horse would go to an experienced rider with a lot of heart...
