Is Staddiscombe too far for you?
Courtgates Farm and Livery are fabulous.
Though I'm not sure if we have any spaces at the moment. If we're near enough for you it's worth the ask.
These might help, www.*******.co.uk and www.*******.co.uk plus ask you farrier vet local saddle shop feed merchant pony club instructor for recommendations.
There’s a place at Bittaford but I don’t know the contact details. It’s up one of the roads under the bridge I believe - you might need to take a drive and explore.
