Kind sharer wanted for my 15.1 cob x mare. Not novice ride

I am looking for a kind, reliable sharer for my cob x mare Annie. She is 15.1 and forward going, not a novice ride. She never does anything silly, never bucks or rears but gets a bit keen sometimes and will occasionally try half heartedly to nap. Good in traffic. Looking for someone to ride once or twice a week, ideally one day at weekend when stable duties will be required during the winter. To stay at present yard in Tilton on the Hill, LE7. Financial contribution required
