Try asking 'Nofie' on this forum, I think she knows a small quiet place in that area.
There is a lovely yard in Hartfield with amazing facilities called Faircote Stud, but its huge.
I'm at a yard in Goudhurst, about 10 mins from T Wells it's amazing and all the people are lovely! This is the link http://www.australianhorsetraining.co.uk/contact.html ring Sarah about livery if you're interested
