putting feelers out

Hi, I am putting out this advert to see if anyone would be interested in a summer loan. I am looking for a horse to enjoy for 3 months at a private yard in Norfolk where my retired happy hacker is kept along with a few liveries. I used to do this a lot when i was a child and now as an adult I am hoping it is something people still do. I am looking for anything from 14-16hh under 17 years old that enjoys hacking, jumping and fun rides. would be perfect for someone who has a ridden horse sitting in a field that is wasted. I also dont mind a green project as long as been broken in at least a year. Horse would be coming to an experienced home.
