ooooo you might have a bit of trouble there - I know there are quite a few people looking around this area and there seems to be a bit of a shortage!
The only one I know of in Milrow is Fenns Riding Centre, and I am not too sure whether they do livery, I just know it because that's where I first started riding
FENNS EQUESTRIAN CENTRE
Fenns Farm, Moor Bank Lane, Milnrow. Tel: 01706-55611
Hope that helps,
