Horse box with paddock

Horse box with paddock - I am looking for a new place for my 15 year old gelding 170cm tall. Best box with paddock and daily run / pasture even in winter.
He is relatively high ranking in the herd. He is not quite easy. Previously he stood with about 20 horses in the herd there it worked out great, there was always one of the boss .who had shown him wherehs lang goes.
In the new herd now he does not get along. There he has the old chased away and partly also put in the corner.... He is believed to be overwhelmed with it.so he now stands with another gelding extra.
Therefore, I am looking for either ne small herd with high ranking horses and in the same age are approximately or only in pairs. He gets along with mares and geldings.

Please within a radius of about 10 to 15km.
Price up to 350€...
